   confidence: boundary (tie-break-unstated)

In Colombo, Holī 2016 falls on Wednesday 23 March. It is kept the day after Holikā Dahana, which falls on Tuesday 22 March. Pūrṇimā runs from 15:13 on Tue 22 Mar to 17:31 on Wed 23 Mar and covers all of sāyāhna on the 22nd. It also reaches the next late afternoon for 95 minutes; the rule does not say which to take, and the one covered longer is ruled. The rule does not settle this date cleanly.

Institutional rulings are recorded with a source address, and are never edited to agree.
