Say it like this

In Doha, Gopāṣṭamī 2002 falls on Tuesday 12 November. Aṣṭamī runs from 11:23 on Mon 11 Nov to 12:31 on Tue 12 Nov and covers all of madhyāhna that midday. It also reaches the previous midday for 19 minutes; the rule does not say which to take, and the one covered longer is ruled. The rule does not settle this date cleanly.
