Say it like this

In Phoenix, Holī 1909 falls on Sunday 7 March. It is kept the day after Holikā Dahana, which falls on Saturday 6 March. Pūrṇimā runs from 17:28 on Fri 5 Mar to 19:56 on Sat 6 Mar and covers all of sāyāhna on the 6th. It also reaches the previous late afternoon for 60 minutes; the rule does not say which to take, and the one covered longer is ruled: treat the date as contested.
