One date per exam
ALP, Technician and Section Controller count age on 1 July 2026, JE and both NTPC streams on 1 January 2027, and Group D on 1 January 2026. Picking the wrong exam can move your age by six months and flip the verdict.

Understand the result
What does an RRB age calculator do?
It counts your exact age — years, months and days — on the crucial date of the RRB exam you choose, and checks it against the age limit for your category. RRB counts age on that one date only, and every exam has its own: 1 July 2026 for ALP, Technician and Section Controller, 1 January 2027 for JE and both NTPC streams, and 1 January 2026 for Group D. Your age on the day you apply, or on the exam day, does not decide eligibility. RRB sets no limit on the number of attempts — only the age limit decides whether you can still appear. And unlike IBPS and UPSC, RRB does not add relaxations together: you get the maximum relaxation you are eligible for, not the sum.
“Must not have attained”
The upper limit is exclusive. Turning 30 on 1 July means you have attained 30 and are over the General limit for ALP — the same wording decides every exam and relaxation on this page.
One relaxation at a time
RRB gives the maximum relaxation you are eligible for, never the sum. An SC ex-serviceman gets 8 years on top of his service deduction — not 5 + 8. The PwBD figures of 10, 13 and 15 years already include the category relaxation.
How it works
From date of birth to your RRB verdict
Start with the date on your Class 10 certificate. Then choose your exam, your category and any extra relaxation.
Enter your date of birth
Use the date on your Class 10 certificate. RRB accepts no other date for determining age.
Choose your RRB exam
NTPC Graduate or Undergraduate, Group D, ALP, Technician Grade I or III, JE/DMS/CMA or Section Controller. Each exam has its own crucial date — the calculator switches to it automatically.
Pick your category and any extra relaxation
SC/ST get 5 years, OBC 3 years. PwBD adds 10, 13 or 15 years in total. Ex-servicemen deduct their service from their age and then add 3, 6 or 8 years. Widows get up to 35, 38 or 40 years; serving railway staff up to 40, 43 or 45. RRB takes the maximum, never the sum.
Read the verdict
Your exact age, the birth-date window for your category, and your first and last eligible exam years. RRB sets no attempt limit, so age is the whole check.
The calculation, explained
How RRB counts your age
The rule is the age section of each RRB CEN: a candidate must be within the stated band on the notification's crucial date. For NTPC Graduate that means 18 to 33 years as on 1 January 2027 — born not earlier than 2 January 1994 and not later than 1 January 2009. Category relaxations raise the upper limit only — the minimum age applies to every category. The upper limit is exclusive: you must not have attained it on the crucial date. Relaxations do not add up: a PwBD candidate gets 10, 13 or 15 years in total depending on category, and an ex-serviceman's service is deducted from the age first, then 3, 6 or 8 years apply.
1. Count completed years
26 completed years
15 March 2000 to 1 January 2027 is 26 full years.
2. Then completed months
9 completed months
From 15 March to 1 January is 9 full months.
3. Then remaining days
17 days
The result is 26 years, 9 months and 17 days — 9,788 days in total.
29 February birthdays fall on 1 March in non-leap years.
Born 29 February 2000, you are 26 years, 4 months and 2 days old on
1 July 2026 and 26 years, 10 months and 3 days old on 1 January 2027. The limits on this page come from the 2026-cycle CENs (01/2026 to 07/2026 and 09/2025); the next cycle will publish new crucial dates, so re-check the rules against the new CEN before you apply.

Inside the limit for NTPC Graduate
Born 15 March 2000, she is 26 years, 9 months and 17 days old on 1 January 2027 — inside 18–33, so eligible for NTPC Graduate as a General candidate. Her first eligible year was 2019 and her last is 2033.

Exactly 30 on the cut-off — over the limit
Born 1 July 1996, he is exactly 30 years old on 1 July 2026. He has attained 30, so he is over the General limit for ALP — but as an OBC candidate the upper limit is 33, and he is eligible. His first eligible year as an OBC candidate was 2014 and his last is 2028.

Disability relaxation, counted once
Born 15 June 1988, she is 37 years, 6 months and 17 days old on 1 January 2026. As an SC candidate with a benchmark disability the upper limit for Group D is 48 — 33 plus 15 for PwBD, which already includes her 5-year SC relaxation — so she is eligible. Her first eligible year was 2007 and her last is 2036.

One birthday, eight different answers
Born 2 July 1993. The age is nearly the same at each crucial date — 33 years, 5 months and 30 days on 1 January 2027 — but the verdict changes with the exam, because the crucial date and the upper limit change.
| Exam | Crucial date | Upper limit | Age on that date | Verdict |
|---|---|---|---|---|
| NTPC Graduate — General | 1 January 2027 | Under 33 years | 33 years, 5 months and 30 days | Over the upper limit |
| NTPC Undergraduate — General | 1 January 2027 | Under 30 years | 33 years, 5 months and 30 days | Over the upper limit |
| Group D / Level 1 — General | 1 January 2026 | Under 33 years | 32 years, 5 months and 30 days | Eligible |
| Assistant Loco Pilot (ALP) — General | 1 July 2026 | Under 30 years | 32 years, 11 months and 29 days | Over the upper limit |
| Technician Grade I Signal — General | 1 July 2026 | Under 33 years | 32 years, 11 months and 29 days | Eligible |
| Technician Grade III — General | 1 July 2026 | Under 30 years | 32 years, 11 months and 29 days | Over the upper limit |
| Junior Engineer / DMS / CMA — General | 1 January 2027 | Under 33 years | 33 years, 5 months and 30 days | Over the upper limit |
| Section Controller — General | 1 July 2026 | Under 33 years | 32 years, 11 months and 29 days | Eligible |
The same person is eligible for Group D, Technician Grade I and Section Controller, and over the limit for both NTPC streams, ALP, Technician Grade III and JE as a General candidate. The exam and the category — not the birthday alone — decide. Always check against the crucial date in your own CEN.
The official rules
RRB age limits, by exam and category
From the age sections of the eight RRB CENs. Every figure is for the 2026 cycle — a new CEN publishes new crucial dates, so re-check before you apply.
| Exam | Crucial date | Age band | Born between |
|---|---|---|---|
| NTPC Graduate (CEN 06/2026) | 1 January 2027 | 18–33 years | 2 January 1994 – 1 January 2009 |
| NTPC Undergraduate (CEN 07/2026) | 1 January 2027 | 18–30 years | 2 January 1997 – 1 January 2009 |
| Group D / Level 1 (CEN 09/2025) | 1 January 2026 | 18–33 years | 2 January 1993 – 1 January 2008 |
| Assistant Loco Pilot (ALP) (CEN 01/2026) | 1 July 2026 | 18–30 years | 2 July 1996 – 1 July 2008 |
| Technician Grade I Signal (CEN 02/2026) | 1 July 2026 | 18–33 years | 2 July 1993 – 1 July 2008 |
| Technician Grade III (CEN 02/2026) | 1 July 2026 | 18–30 years | 2 July 1996 – 1 July 2008 |
| Junior Engineer / DMS / CMA (CEN 04/2026) | 1 January 2027 | 18–33 years | 2 January 1994 – 1 January 2009 |
| Section Controller (CEN 03/2026) | 1 July 2026 | 20–33 years | 2 July 1993 – 1 July 2006 |
| Category | Relaxation | Upper age limit for NTPC Graduate |
|---|---|---|
| General | — | Under 33 years |
| EWS | — | Under 33 years |
| OBC (non-creamy layer) | +3 years | Under 36 years |
| SC | +5 years | Under 38 years |
| ST | +5 years | Under 38 years |
| Relaxation | How much | Notes |
|---|---|---|
| Person with benchmark disability (PwBD) | +10 / +13 / +15 years | Total, including the category relaxation: PwBD (General/EWS) get 10 years, PwBD (OBC) 13 years and PwBD (SC/ST) 15 years. The ALP CEN has no PwBD row, so this choice is not offered for ALP. |
| Ex-serviceman | Service deducted, then +3 / +6 / +8 years | Your service is deducted from your age first, then 3 years (General/EWS), 6 years (OBC) or 8 years (SC/ST) are added to the upper limit. Needs more than six months of service after attestation. No maximum-age cap. |
| Widow, divorced or legally separated woman (not remarried) | Up to 35 / 38 / 40 years | Every CEN. The upper limit becomes 35 years (General/EWS), 38 years (OBC) or 40 years (SC/ST). |
| Serving railway staff, casual labour or substitute (3+ years of service) | Up to 40 / 43 / 45 years | Every CEN. Group C and erstwhile Group D railway staff, casual labour and substitutes with minimum 3 years of service: the upper limit becomes 40 years (General/EWS), 43 years (OBC) or 45 years (SC/ST). |
| Course Completed Act Apprentice (CCAA) | Training period, up to 3 years | ALP, Technician Grade III and Group D only. Relaxed by the apprenticeship training undergone, up to 3 years (General/EWS), 6 years (OBC) or 8 years (SC/ST) in total including the category relaxation. Railway establishments only. |
| Course Completed Act Apprentice who became one before age 25 | Up to 35 / 38 / 40 years | ALP, Technician Grade III and Group D only. The upper limit becomes 35 years (General/EWS), 38 years (OBC) or 40 years (SC/ST). |
Two maximum-rule examples: an SC ex-serviceman with 10 years of service is counted at his age minus 10 years against 33 + 8 = 41 years for NTPC Graduate — the 8 already includes his 5-year SC relaxation. An OBC candidate with a benchmark disability gets 33 + 13 = 46 years. Only one extra relaxation is applied at a time on this page — the CENs give the maximum, not the sum.
Common mistakes
Four ways to read the age limit wrong
The RRB age rules are short, but four readings trip people up every cycle. Each one can make an eligible candidate apply late or an over-age candidate waste an application.
Counting from the exam date
The age is fixed on the crucial date, not the exam date. An ALP candidate who turns 30 in September 2026 is still under 30 on 1 July 2026 — and eligible.
Reading 30 as “up to 30”
The limit is exclusive: you must not have attained 30. Born 1 July 1996, you are exactly 30 on 1 July 2026 and over the General limit for ALP; born 2 July 1996, you are eligible.
Using another exam’s cut-off
NTPC counts on 1 January 2027, Group D on 1 January 2026, ALP on 1 July 2026. Using NTPC’s date for an ALP application moves your age by six months and can flip the verdict.
Adding relaxations together
RRB gives the maximum relaxation, not the sum. An SC candidate with a benchmark disability gets 15 years in total, not 5 + 15. Adding them overstates your limit by years.
Your questions, answered
RRB age calculator FAQs
What is the cut-off date for RRB age calculation?
It depends on the exam. ALP, Technician and Section Controller count age on 1 July 2026, JE and both NTPC streams on 1 January 2027, and Group D on 1 January 2026. It is not the exam date and not the day you apply. Your age on that one date decides eligibility.
I turn 30 on 1 July 2026 for ALP. Am I eligible?
No. The CEN says you must have been born not earlier than 2 July 1996. Born 1 July 1996, you are exactly 30 on 1 July 2026 and over the General limit. Born 2 July 1996, you are 29 years, 11 months and 29 days old and eligible. The same exclusive rule applies to every RRB exam on this page.
How do the age relaxations work — do they add up?
No. RRB gives you the maximum relaxation you are eligible for, not the sum of them. A PwBD candidate gets 10 years (General/EWS), 13 years (OBC) or 15 years (SC/ST) in total — the category relaxation is already inside those figures. An SC ex-serviceman with 10 years of service is counted at his age minus 10 years against an upper limit of 33 + 8 = 41 years for NTPC Graduate — the 8 already includes his 5-year SC relaxation. A candidate who is both a widow and railway staff gets the higher of the two limits — 40 years, not 35 + 40. Pick the one extra relaxation that gives you the most, and the calculator applies it.
How does the ex-serviceman relaxation work?
Your service is deducted from your age first, and then 3 years (General/EWS), 6 years (OBC) or 8 years (SC/ST) are added to the upper limit. You need more than six months of service after attestation. There is no maximum-age cap for ex-servicemen. Example: an SC ex-serviceman with 10 years of service applying for NTPC Graduate is counted at his age minus 10 years against an upper limit of 41 years.
Is there a limit on the number of RRB attempts?
No. None of the eight CENs states a limit on the number of attempts. You can appear every year for as long as you stay inside the age limit for your category. That is why this calculator shows first and last eligible exam years instead of attempts.
What are my first and last eligible exam years?
The first year you can appear is the first year in which you meet the minimum age on that exam's crucial date; the last year is the last year in which you are still under your upper limit on the crucial date. They assume the crucial date falls on the same date each year, as it has in recent cycles. Born 15 March 2000 as a General candidate for NTPC Graduate, your first eligible year is 2019 and your last is 2033.
My birthday is 29 February. How is my age counted?
Your birthday falls on 1 March in a non-leap year — the same rule the SSC Age Calculator and the Age Calculator on this site use. Born 29 February 2000, you are 26 years, 4 months and 2 days old on 1 July 2026 and 26 years, 10 months and 3 days old on 1 January 2027. If your eligibility turns on that single day, confirm it with RRB before applying.
Why isn't Paramedical (CEN 05/2026) in this calculator?
The Paramedical CEN covers nine posts with six different age bands — Nursing Superintendent 20–40, Pharmacist 20–35, Audiologist 21–30, Radiographer 19–33 and the rest 18–33, all as on 1 January 2027. One exam choice cannot represent them, so this page leaves Paramedical out rather than guessing. Check the per-post table in CEN 05/2026 on rrb.indianrailways.gov.in.
Does this check my education, qualification or medical standard?
No. This tool checks age only. You also need the qualification each CEN asks for — a degree for NTPC Graduate, JE and Section Controller, 12th pass for NTPC Undergraduate, 10th or ITI for Group D, ALP and Technician Grade III — and the medical standard of the post. Only the CEN on rrb.indianrailways.gov.in decides your eligibility.
About the method
This page applies the age sections of the eight RRB detailed CENs for the 2026 cycle: CEN 01/2026 ALP (1 July 2026), CEN 02/2026 Technician (1 July 2026), CEN 03/2026 Section Controller (1 July 2026), CEN 04/2026 JE/DMS (1 January 2027), CEN 06/2026 NTPC Graduate (1 January 2027), CEN 07/2026 NTPC Undergraduate (1 January 2027) and CEN 09/2025 Group D (1 January 2026). CMA posts were added to the JE CEN by Corrigendum No. 1 and share the JE band. Paramedical (CEN 05/2026) is not included: its nine posts carry six different age bands, so one exam choice cannot represent them. The quasi-administrative offices relaxation, present in the CENs, is not modelled: its interaction with the maximum rule is ambiguous and the group is small.
Age is counted by calendar subtraction on Gregorian dates: complete years, then complete months, then the remaining days, with borrowing from the previous month. Dates are counted in UTC, so the result is the same in every time zone. A 29 February birthday falls on 1 March in a non-leap year — the same rule the SSC Age Calculator on this site uses. No exam body endorses this tool, and it checks age only.
