Say it like this

In Luanda, Holī 2077 falls on Wednesday 10 March. It is kept the day after Holikā Dahana, which falls on Tuesday 9 March. Pūrṇimā runs from 16:15 on Mon 8 Mar to 18:44 on Tue 9 Mar and covers all of sāyāhna on the 9th. It also reaches the previous late afternoon for 128 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested.
