24-Hour Clock (Railway Time)

12-hour clock: 12 AM (midnight) to 12 PM (noon), then 12 PM to 11 PM. Confusing! 24-hour clock: runs from 00:00 (midnight) to 23:59. No AM/PM needed. Morning 7 AM = 07:00. Noon 12 PM = 12:00. Evening 6 PM = 18:00 (12+6). Night 11 PM = 23:00. Midnight = 00:00 (not 24:00). Indian Railways uses 24-hour clock — that is why your train ticket shows "18:30" not "6:30 PM".
