Say it like this

In Luanda, Holī 1952 falls on Wednesday 12 March. It is kept the day after Holikā Dahana, which falls on Tuesday 11 March. Pūrṇimā runs from 17:47 on Mon 10 Mar to 19:14 on Tue 11 Mar and covers all of sāyāhna on the 11th. It also reaches the previous late afternoon for 36 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested.
