Festival demand cuts cancellations sharply, so waitlists move less than usual. Check the honest odds for your GNWL, RLWL or PQWL number before you decide whether to gamble on Tatkal.
Every Malayali outside Kerala tries to be home for Thiruvonam. Bengaluru, Chennai and Mumbai to Kerala is the corridor, and the Kerala-bound trains fill on the first morning.
Bengaluru, Chennai, Mumbai, Hyderabad and Delhi to Ernakulam, Thrissur, Kozhikode, Kottayam, Kollam and Thiruvananthapuram.
Onam 2027 falls on Sunday, 12 September 2027. Under the 60-day Advance Reservation Period, general booking for travel on that day opens on Wednesday, 14 July 2027 at 08:00 IST. For the busiest outbound day, 10 September 2027, booking opens on 12 July 2027. Each journey date opens on its own day, 60 days ahead, so the tables above list every date in the rush.
General-quota reservation opens at 08:00 IST on the day the 60-day window reaches your journey date. Tatkal is separate: it opens at 10:00 IST for AC classes and 11:00 IST for Sleeper and other non-AC classes, one day before the journey. Only Aadhaar-authenticated IRCTC accounts can book Tatkal online.
Tatkal opens one day before each journey date. For travel on 10 September 2027, that is 9 September 2027 — 10:00 IST for AC classes and 11:00 IST for Sleeper. The Tatkal quota is small and festival demand is extreme, so treat it as a backup to a general booking made on the day the window opened, not as the plan.
Book immediately even if the train shows a waitlist — a low GNWL number booked early still confirms on most trains, and the queue only gets longer. Then check the confirmation odds for your waitlist code, and note the Tatkal date for the same journey as a fallback one day before travel.
Not always. Festival specials are notified separately, often only a few weeks before they run, and their booking opens when the notification says, which can be shorter than 60 days. The dates on this page are for regular trains. Check the IRCTC and zonal railway announcements for specials on your route once the festival is a few weeks away.
Set by the lunar calendar; a regional panchang can differ by a day. The dates here were checked against Drik Panchang and the mainstream Indian calendars. If your family follows a regional calendar that puts the festival a day earlier or later, use the tables to read off the booking date for that day instead.

Scope: Festival dates are taken from the published panchang and can differ by a day between regional calendars. Booking dates follow the 60-day Advance Reservation Period for regular trains; festival special trains are notified separately with their own windows.
