   confidence: boundary (tie-break-unstated)

In Doha, Holī 1987 falls on Sunday 15 March. It is kept the day after Holikā Dahana, which falls on Saturday 14 March. Pūrṇimā runs from 15:44 on Sat 14 Mar to 16:13 on Sun 15 Mar and covers 117 of 143 minutes of sāyāhna on the 14th. It also reaches the next late afternoon for 54 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.
