Say it like this

In Baoding, Vijayā Daśamī (Dussehra) 2061 falls on Monday 24 October. Daśamī touches Śravaṇa in the day time on neither day, so madhyāhna decides. Daśamī runs from 12:25 on Sun 23 Oct to 12:52 on Mon 24 Oct and covers all of madhyāhna that midday. It also reaches the previous midday for 1 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested. It is 1 min 02 s from a threshold: treat the date as contested.
