How Many Days Until Mardi Gras 2028?

Mardi Gras 2028 is Tuesday, 29 February 2028

There are 550 days between 28 August 2026 and Mardi Gras 2028, which falls on Tuesday, 29 February 2028. That is 78 weeks and 4 days, or 373 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 2028-02-29 in ISO form and 2/29/2028 in the US format, it falls in ISO week 9 of 2028, and it is day 60 of 366.

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 2028 it works out as Tuesday 29 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 373 working days above.
