Frequently Asked Questions

When does IRCTC booking open for a train?

IRCTC booking opens exactly 60 days before the journey date (from the train's origin station) at 8:00 AM IST. Tatkal booking opens 1 day before — AC classes at 10:00 AM IST and Sleeper at 11:00 AM IST.

How do I calculate T-60 booking date?

Subtract exactly 60 calendar days from your journey date. That is your T-60 date. IRCTC opens booking at 8:00 AM IST on that day. Use our free Booking Window Calculator above to get the exact date instantly.

How much refund will I get on IRCTC cancellation?

The refund depends on when you cancel. 72+ hours before departure: only a flat clerkage charge. 24–72 hours: 25% of fare or the flat charge, whichever is more. 8–24 hours: 50% of fare. Less than 8 hours: no refund for confirmed tickets.
