In Paramaribo, Holī 2005 falls on Saturday 26 March. It is kept the day after Holikā Dahana, which falls on Friday 25 March.

It also reaches the previous late afternoon for 89 minutes; the rule does not say which to take, and the one covered longer is ruled. The rule does not settle this date cleanly.
