Happy Ayyám-i-Há

[essentialsaltes]

In the Bahá'í calendar, the Festival of Ayyám-i-Há celebrates the 4 (or 5) intercalary days that round out their calendar of 19 months of 19 days. The days run from "sunset of February 25 to sunset of March 1" (conveniently making leap years automatically accounted for).
