Cinco de Mayo 2026 has already happened. It was Tuesday, 5 May 2026, 115 days ago. This page is kept whichever side of today the date falls on: the date and the rule behind it are worth looking up either way. For the year after this one see Cinco de Mayo 2027, and for the always-current countdown see the next Cinco de Mayo.
Cinco de Mayo 2026 is Tuesday, 5 May 2026
Cinco de Mayo 2026 fell on Tuesday, 5 May 2026, which was 115 days before 28 August 2026. That is 16 weeks and 3 days, or 80 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 2026-05-05 in ISO form and 5/5/2026 in the US format, it falls in ISO week 19 of 2026, and it is day 125 of 365.
How the date of Cinco de Mayo is decided
Cinco de Mayo is always 5 May.
That makes it a fixed date: the same day of the same month every year, so it lands on a different weekday each time. In 2026 it is a Tuesday.
Cinco de Mayo 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.
Cinco de Mayo in the years after 2026
| Year | Date | Day | Countdown |
|---|---|---|---|
| 2027 | 5 May 2027 | Wednesday | Cinco de Mayo 2027 |
| 2028 | 5 May 2028 | Friday | Cinco de Mayo 2028 |
| 2029 | 5 May 2029 | Saturday | Cinco de Mayo 2029 |
The date does not move, but the weekday does — which is why the same holiday gives a long weekend in some years and not others.
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 80 working days above.
