How Many Days Until Ash Wednesday?

Ash Wednesday 2027 is Wednesday, 10 February 2027

There are 175 days between 19 August 2026 and Ash Wednesday, which falls on Wednesday, 10 February 2027. That is exactly 25 weeks, or 118 working days once Saturdays, Sundays and the US federal holidays in between are taken out — the figure that matters if you are counting delivery lead time or a work schedule rather than sleeps. The date is 2027-02-10 in ISO form and 2/10/2027 in the US format, it falls in ISO week 6 of 2027, and it is day 41 of 365.

How the date of Ash Wednesday is decided

Forty-six days before Easter Sunday — forty fasting days plus the six Sundays, which are not counted.

That makes it a computed date: there is no fixed day and no simple weekday rule, so it has to be worked out from a formula or a calendar of its own each year. In 2027 it works out as Wednesday 10 February.

Ash Wednesday is an observance rather than a federal holiday. Offices, banks and schools stay open unless an individual employer chooses otherwise, and it counts as an ordinary business day in every calculator here. Only the eleven federal holidays are treated as non-working days — the list and the reasoning are on the holiday sources page.

Both the date and the weekday move, because the rule is not tied to either.

Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including how we count the 118 working days above.
