Say it like this

In Daegu, Holī 2078 falls on Tuesday 29 March. It is kept the day after Holikā Dahana, which falls on Monday 28 March. Pūrṇimā runs from 17:53 on Sun 27 Mar to 20:06 on Mon 28 Mar and covers all of sāyāhna on the 28th. It also reaches the previous late afternoon for 50 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested.
