If you are planning to travel home for Diwali 2026 (Dhanteras is on 6 November, Diwali on 8 November), you probably already know the problem: trains on popular routes fill up within minutes of booking opening. This guide explains how the booking window works, how to calculate when tickets opened, when Tatkal opens, and what you can still do today, 7 October 2026, if you do not have a confirmed seat.
Quick answer
- Indian Railways' advance reservation period (ARP) is 60 days, not counting the day of travel. Reservation for most trains opens at 8 AM on the first day of the window.
- For Diwali travel on 4 to 8 November, booking opened between 5 and 9 September. Those dates are gone, so what is available today is cancellations, waitlist and RAC tickets, and Tatkal closer to the date.
- Tatkal opens one day before the journey (excluding the journey date) at 10 AM for AC classes and 11 AM for non-AC classes, for the train's originating station.
- Online Tatkal booking requires an Aadhaar-authenticated IRCTC account, and an Aadhaar-linked OTP step has been brought in for Tatkal.
How to calculate when booking opened
The rule of thumb: count back 60 days from your date of journey. The day you reach is the day booking opens. For the dates around Diwali:
| Journey date | Booking opened (60 days earlier) |
|---|---|
| Wednesday, 4 November | Saturday, 5 September |
| Friday, 6 November (Dhanteras) | Monday, 7 September |
| Sunday, 8 November (Diwali) | Wednesday, 9 September |
| Tuesday, 10 November (Bhai Dooj) | Friday, 11 September |
| Thursday, 12 November | Sunday, 13 September |
Today, 7 October, the furthest date you can book is 6 December. If you are planning for Christmas, New Year or the winter holidays, count back in the same way and set a reminder for 7:55 AM on the opening day.
What to do if you are waitlisted
- Check the chart prospects. A low waitlist number (for example WL 1 to WL 20) on a popular train often clears as people cancel, especially in the days before departure. A high number may not.
- Check alternatives on the same route. Search the day before and the day after, and nearby stations, or break the journey into two legs through a junction.
- Look for special trains. Indian Railways usually announces festival special trains for Diwali and Chhath. Check the IRCTC website and the zonal railway announcements, as special trains often have fresh quotas.
- Try Tatkal and Premium Tatkal. These are costlier, but give you a confirmed seat if you are quick.
- Watch for current availability. After the chart is prepared, a "current" booking window may show vacant berths.
- Keep a bus or flight fallback for a day or two earlier or later than the festival peak, because prices and demand are lowest outside the peak days.
Tatkal in more detail
| Rule | Detail |
|---|---|
| Opens | One day before the journey date, for the train’s originating station |
| AC classes (2A, 3A, CC, EC, 3E) | 10:00 AM |
| Non-AC classes (SL, FC, 2S) | 11:00 AM |
| Online booking | Needs an Aadhaar-authenticated IRCTC account; an Aadhaar-linked OTP has been made part of the Tatkal process |
| Offline (PRS counter) | From 1 August 2026 a token-based system was reported for counters, with tokens issued before the window opens and a valid photo ID needed |
The Tatkal timings are the same at the time of writing. If you see a viral message claiming a change, check it on the IRCTC website or the Railway Ministry channels. IRCTC has previously had to deny false social media claims about Tatkal rule changes.
Booking tips that genuinely help
- Save passenger details in your IRCTC profile in advance and use the master list.
- Complete Aadhaar authentication before the window and keep your payment method ready: UPI, net banking or the IRCTC wallet.
- Have a stable internet connection and log in a few minutes early. Do not refresh repeatedly.
- Use the official IRCTC website and the IRCTC Rail Connect app only. Fake ticketing websites and apps exist.
- Do not pay anyone who promises a "guaranteed confirmed ticket". Touts and unofficial agents are a common source of fraud. If in doubt, report on the railway helpline 139.
Cancellation and refund basics
Refunds depend on the class, how close to departure you cancel, and whether the ticket is confirmed, RAC or waitlisted. Waitlisted e-tickets that remain unconfirmed after chart preparation are automatically cancelled and refunded, minus a clerkage charge. Tatkal tickets that are cancelled are generally not refunded for confirmed bookings. Check the latest rules on the IRCTC site before you pay.
Frequently asked questions
