Ashura
Ashura falls on 10 Muharram each Hijri year. Because the Hijri calendar is lunar and about eleven days shorter than the Gregorian year, its Gregorian date moves earlier each year.
By tabular reckoning, Ashura next falls on (1449 AH). The observed date is set by the sighting of the new crescent and may differ by a day — follow your local authority.

Why the date moves
The Hijri calendar is lunar. Twelve lunar months come to about 354 days — roughly eleven fewer than a solar year — and no adjustment is made to keep the two aligned. So Ashura falls about eleven days earlier in the Gregorian calendar each year, and works its way through all four seasons over roughly 33 years. Its Hijri date, 10 Muharram, never changes.
