What the advance reservation period actually means
Every reserved ticket has a first day on which it can be booked. Indian Railways calls the gap between that day and the journey the advance reservation period, and most people shorten it to ARP. At the moment, the ARP for general reservations is 60 days, and the journey day itself is not counted.
In practice that means if you want to travel on 25 December, booking opens on 26 October at 8 in the morning. Not on the 25th of October, and not at midnight. If you try even a few hours early, IRCTC will tell you the date is outside the range.
The change from 120 days to 60 days
| Period | ARP | What happened |
|---|---|---|
| Until 31 Oct 2024 | 120 days | The old four-month window people still remember |
| From 1 Nov 2024 | 60 days | Current rule for general reservations, journey day excluded |
| Tatkal | 1 day | Opens the day before the journey, at 10:00 AM (AC) or 11:00 AM (non-AC) |
Tickets that were already booked under the 120-day rule stayed valid. That is why you may still see an older relative holding a ticket booked "three months ahead". It was legal then; it is not possible today.
How to use the date the calculator gives you
- Find the date your train leaves its origin station, not the date you board.
- Put that date in the calculator above and note the opening date.
- Add a reminder for 07:45 AM so you are logged in before 8:00 AM.
- Keep passengers saved in your IRCTC master list so checkout takes seconds.
Common mistakes that look like ARP problems
- Counting 60 days from the wrong day. Always count back from the journey date itself.
- Using the boarding date for a train that started the previous day. The window follows the origin date.
- Trying at 7:59 AM. The window opens at 08:00 AM IST, not before.
- Expecting the 2 or 4 month rule. It is 60 days now, even though older websites still say otherwise.

Quick FAQ
What is the advance reservation period (ARP) in IRCTC?
ARP is the number of days before the journey date from which Indian Railways allows you to reserve a ticket. For most trains it is 60 days, not counting the day of journey. Booking for a journey date opens at 08:00 AM IST on the 60th day before it.
What is the ARP in Indian Railways now?
60 days for general reservations. It was 120 days until 31 October 2024 and was cut to 60 days from 1 November 2024. Tickets booked under the old 120-day rule were not cancelled.
What does 'journey date is not within ARP range' mean?
You picked a date that is still more than 60 days away, so booking has not opened for it yet. Use the calculator above to see the exact opening date, set a reminder, and try again at 08:00 AM IST that day.
Is the ARP counted from my boarding station or the origin station?
From the origin station of the train. If you board mid-route, the date your journey starts for you can be a day later than the date the train left its origin, so your booking may open a day later than the calculator shows for the origin date.
Is there a 2 month or 4 month advance booking now?
No. 4 months (120 days) was the old rule and 2 months (60 days) is the current one. People still search for both, which is why you keep seeing them.
Does a foreign tourist get a different ARP?
Foreign tourists have historically had a much longer window (365 days). Check the IRCTC foreign tourist booking page for the current position, because that category follows its own rule.
