St. Patrick's Day is March 17, a cultural and religious feast day that is not a US federal holiday. DaysUntil counts to your local March 17, then rolls to the next March 17 after the date ends. In 2026 the 17th is a Tuesday; in 2027 it is a Wednesday. Ireland treats the day as a public holiday. US parades are municipal events and sometimes move to a Saturday; this page stays on March 17 so a shared link means the feast date, not a city's march.

FAQ

When is St. Patrick's Day?
March 17 every year. After that local date ends, we roll to next March 17. 2026 is a Tuesday; 2027 is a Wednesday. The heading stays yearless.
Is it a US federal holiday?
No. It is a public holiday in the Republic of Ireland and in Northern Ireland. American parades, river dyeings, and pub crawls are local. Federal offices stay open.
Does the date ever move?
The feast is March 17. Church calendars may shift liturgy when it falls in Holy Week; civic parades sometimes move to the nearest Saturday for crowds. Those are not the civil date this page uses.
Why might another site disagree?
A parade-Saturday countdown is not the feast date. A UTC flip near midnight can also shift the number. We use local March 17 through the end of that day.
What is the distinctive history for a US countdown?
Patrick's fifth-century mission is the religious root; the American civic overlay is later. Unique to this page: New York's parade claims a colonial-era start, but the nineteenth-century Irish-American fraternal march is what turned March 17 into a US street holiday — which is why the feast is Irish and the all-day civic spectacle is especially American.
Should I count to a parade step-off?
Use a custom time for a specific city's march. This page stays on March 17.
What if Holy Week collides with March 17?
Church liturgies may transfer the feast when March 17 falls in Holy Week; city parades may already have moved to Saturday for crowds. Those transfers are real and local. This slug stays on March 17 so a nationwide link does not silently become “the Saturday the city preferred.” Build extra clocks for the transferred liturgy or the march.
Why do US cities dye rivers if the feast is Irish?
Chicago's river dyeing is a local civic stunt from the 1960s, not a liturgical requirement. It shows how March 17 became an American municipal festival layered on an Irish saint's day. Count to March 17 here; count to the dyeing hour with a custom time if that is the spectacle you mean.
