   Rule

   Daśamī touches Śravaṇa in the day time on neither day, so the rest of the rule applies. Daśamī must be present during madhyāhna. It covers 48 of 48 minutes on the 25th and 31 of 48 on the 26th.

   Ruling

   confidence: boundary (tie-break-unstated)

Say it like this

In Daqing, Vijayā Daśamī (Dussehra) 2020 falls on Sunday 25 October. Daśamī touches Śravaṇa in the day time on neither day, so madhyāhna decides. Daśamī runs from 10:12 on Sun 25 Oct to 11:31 on Mon 26 Oct and covers all of madhyāhna that midday. It also reaches the next midday for 31 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested.
