Mardi Gras 2026 has already happened. It was Tuesday, 17 February 2026, 183 days ago. This page is kept because the date and the rule behind it are still worth looking up — for the live countdown, go to Mardi Gras 2027, or to the always-current countdown.
Mardi Gras 2026 is Tuesday, 17 February 2026
Mardi Gras 2026 fell on Tuesday, 17 February 2026, which was 183 days before 19 August 2026. That is 26 weeks and 1 day, or 128 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 2026-02-17 in ISO form and 2/17/2026 in the US format, it falls in ISO week 8 of 2026, and it is day 48 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 2026 it works out as Tuesday 17 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.

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 128 working days above.
