IRCTC Ticket Booking Date Calculator : IRCTC Ticket General Quota and Tatkal Quota booking date calculator.
The Ministry of Railways decided to increase the advance reservation period from 60 Days to 120 Days(excluding the date of journey) with effect from 1.4.2015. Advance reservations are made generally up to 120 days in advance for all classes and all trains. The period of advance reservation (ARP) is exclusive of the day of departure of the train. At intermediate stations where the train arrives on the following day, such reservations can be done more than 120 days in advance of date of journey from the intermediate station. ARP is in relation to the date of journey from train originating station. In case of some Inter-city day trains, the ARP is less.
Important Note: The calculation of above dates are assumed that the train starts from the originating station on the same day.
