How Many Days Until Mardi Gras 2029?

Mardi Gras 2029 is Tuesday, 13 February 2029

There are 909 days between 19 August 2026 and Mardi Gras 2029, which falls on Tuesday, 13 February 2029. That is 129 weeks and 6 days, or 620 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 2029-02-13 in ISO form and 2/13/2029 in the US format, it falls in ISO week 7 of 2029, and it is day 44 of 365.

How the date of Mardi Gras is decided

Shrove Tuesday, the day before Ash Wednesday and forty-seven days before Easter.

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 2029 it works out as Tuesday 13 February.

Mardi Gras 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 620 working days above.
