I am a bit confused about the refund. I have booked three 3AC birth in CST - Patna Premium Superfast train round 20 days back for 23rd May 2017 Train departure is 11:05 AM. What be fare deduction rule if i cancel ticket on 21st May 9 AM, 21st May 9 PM and on 22nd May 9 AM or 22nd May 9 PM. It is not under Tatkal or Premium Tatkal Quota.
