How do I find out what holiday is on a date?

Pick the date: the tool lists every holiday and observance on it, from federal holidays to UN international days, each with its kind. It opens on today, so it also answers what holiday is today.

Which holidays does the tool list?

The US federal holidays and their observed days; a selection of the national observances in Title 36 of the US Code, such as Flag Day and Patriot Day; days kept on a fixed date by custom, such as Valentine's Day and Halloween; Tax Day and Election Day; Easter and the days counted from it, and Orthodox Easter; the main Jewish holidays; the equinoxes, solstices and daylight saving time changes; and the UN international days.

Why isn't National Pizza Day or another national food day listed?

Because no law or public body sets those dates: the "national day" lists for foods and causes come from private calendars and brands, and different lists give different days. The tool lists only days whose date comes from a rule or a public source it names.

Does the tool list state holidays or other countries' holidays?

No. It covers the US federal holidays, US observances, Easter, the Jewish holidays, the seasons and the UN days. State holidays, other countries' public holidays and holidays whose date depends on sighting the moon, such as Eid al-Fitr, are not listed.

When do Jewish holidays start?

At sundown on the evening before the date shown, because a day in the Hebrew calendar starts at sunset. Rosh Hashanah 2027, 1 Tishrei, falls on Saturday, October 2, 2027, so it begins on the evening of October 1, 2027.

Why does Easter move every year?

Because it follows the moon: Easter Sunday is the first Sunday after the church's full moon on or after March 21, so it falls between March 22 and April 25. It is March 28, 2027, and April 16, 2028 the year after. Good Friday is two days earlier and Ash Wednesday 46 days earlier.

Why is the September equinox on September 22 in some places and September 23 in others?

Because it is a single moment, and the date depends on the clock you read it on. In 2026 it came at 8:05 PM Eastern Time on September 22, which was already September 23 in UTC. The tool dates the seasons on the US Eastern clock and gives the UTC time beside them.

Are UN international days public holidays?

No. An international day marks a cause the UN wants to draw attention to, such as World Health Day on April 7; schools and offices stay open. No country is required to give a day off for one.

Is a federal holiday on a weekend moved?

For federal employees, yes: a holiday on a Saturday is observed on the Friday before, and one on a Sunday on the Monday after. The tool shows the holiday on its own date with the observed day beside it, and lists the observed day under its own date too.

Can I share the holidays of a date?

Yes. Copy the link under the result: it carries the date, so whoever opens it sees the same holidays.

Holidays by Date

Pick any date and see what holiday it is: every US federal holiday and its observed day, the observances set by law or custom, Easter and the Jewish holidays, the equinoxes and solstices and the UN international days on it, each with its kind and the weekday. The next holiday after the date comes with it, and the dates people look up most, such as September 23 and April 6, have pages of their own.

How DateMath finds the holidays on a date

DateMath lists only days whose date comes from a rule or a public source it names. It works out every rule for the year you pick: the 11 federal holidays of 5 U.S.C. 6103 with their observed days, a selection of the observances Congress set in Title 36 of the US Code, such as Flag Day and Armed Forces Day, and the ones kept on a fixed date by custom, Easter by the Gregorian computus, the Jewish holidays from the Hebrew calendar in your browser, and the equinoxes and solstices from the US Naval Observatory's table, dated on the US Eastern clock. The UN international days come from the UN's own list. "National days" for foods and causes from private calendars are left out.

US federal holidays. DateMath skips the 11 annual holidays of 5 U.S.C. 6103 on the days they are observed for federal employees, as the US Office of Personnel Management (OPM) lists them: a Saturday holiday on the Friday before, a Sunday holiday on the Monday after. Source: 5 U.S.C. 6103, OPM federal holidays.
US observances set by law. DateMath dates a selection of the national observances Congress has designated in Title 36 of the US Code, such as Flag Day, Mother's Day and Patriot Day, by the rule each one's section gives, Election Day by 2 U.S.C. 7, Tax Day by 26 U.S.C. 7503 (April 15, moved past a weekend or a Washington, D.C. holiday) and the daylight saving time changes by 15 U.S.C. 260a. These are days of note, not days off. Source: 36 U.S.C. chapter 1, 26 U.S.C. 7503.
The date of Easter. DateMath computes Easter Sunday with the Gregorian computus, the church's tables in arithmetic form: the first Sunday after the church's full moon on or after March 21, so between March 22 and April 25. Mardi Gras, Ash Wednesday, Palm Sunday and Good Friday are counted from it, and Orthodox Easter uses the same rule in the Julian calendar. Source: Date of Easter.
The Hebrew calendar. DateMath reads Hebrew dates from the Hebrew calendar data built into your browser (the Unicode CLDR and ICU data every major browser ships). The Hebrew year has 12 months, or 13 in 7 of every 19 years, when Adar I is added before Adar II, and its day starts at sunset. A bar mitzvah is at 13; a bat mitzvah is at 12 in Orthodox communities and often at 13 in others. Source: Hebrew calendar, Bar and bat mitzvah.
Equinoxes and solstices. DateMath takes the moment of each equinox and solstice from the US Naval Observatory's table, in UTC to the minute, and dates it on the US Eastern clock. Near midnight the date differs between time zones. Source: USNO Earth's Seasons.
UN international days. DateMath lists the international days with a fixed date as the United Nations' own list gives them; days the UN moves from year to year, such as World Habitat Day, are left out. They mark a cause, not a day off. Source: UN list of international days.

DateMath's date math is tested against more than 100 cases worked out by hand. Every worked example and table on the site is computed with the same code the calculators run, so a page and its calculator can't disagree.

Holidays on the dates people look up most

These dates have a page each, with their holidays in 2026 and 2027, the moving holidays that land on them in the coming years and the holidays just before and after. In 2027:

September 23 holidays: a Thursday, September equinox: fall begins and a UN international day.
April 6 holidays: a Tuesday, no US holiday or observance and a UN international day.
March 9 holidays: a Tuesday, U.S. Hostage and Wrongful Detainee Day.
April 27 holidays: a Tuesday, Passover.
August 3 holidays: a Tuesday, no US holiday or observance.
April 14 holidays: a Wednesday, no US holiday or observance and a UN international day.
April 21 holidays: a Wednesday, no US holiday or observance and a UN international day.
August 25 holidays: a Wednesday, no US holiday or observance.

What the tool lists, and what it leaves out

A date can carry several kinds of day, and the tool names the kind of each, because they mean different things: a federal holiday closes federal offices, an observance is a day of note that nobody gets off by law.

Federal holiday: the 11 days of 5 U.S.C. 6103, on their own date and on the weekday they are observed when they fall on a weekend, the same days the US federal holidays tool lists.
Observance: a selection of the national days Congress set in Title 36 of the US Code, such as Flag Day and Patriot Day, Tax Day and Election Day, and days kept on a fixed date by custom, such as Valentine's Day, Halloween and Black Friday.
Religious holiday: Easter and the days counted from it, Orthodox Easter, and the main Jewish holidays. Christmas is a federal holiday, so it is listed as one.
Clock change and Season: the start and end of daylight saving time, and the equinoxes and solstices with their time.
UN international day: the days with a fixed date on the UN's own list, from 2026.

Left out: state holidays, other countries' public holidays, holidays whose date depends on sighting the moon (Eid al-Fitr, Eid al-Adha) or on a calendar the tool doesn't compute (Diwali, Lunar New Year), and the "national day" lists for foods and causes, whose dates come from private calendars rather than a rule or a public body. The tool takes dates from 1978, the first year all of today's federal holiday dates applied, to 2099. Days that started later, such as Juneteenth (2021) or Patriot Day (2002), are listed from their first year.

How the moving holidays are worked out

Easter and the days that hang on it

Easter Sunday is the first Sunday after the church's full moon on or after March 21, which the Gregorian computus turns into arithmetic on the year. Mardi Gras is 47 days before it, Ash Wednesday 46, Palm Sunday 7 and Good Friday 2. Orthodox churches apply the same rule in the Julian calendar, so their Easter is the same Sunday or up to five weeks later.

Year	Easter Sunday	Good Friday	Ash Wednesday	Orthodox Easter
2027	March 28	March 26	February 10	May 2
2028	April 16	April 14	March 1	April 16
2029	April 1	March 30	February 14	April 8
2030	April 21	April 19	March 6	April 28
2031	April 13	April 11	February 26	April 13
2032	March 28	March 26	February 11	May 2

Jewish holidays start at sundown

The Jewish holidays are fixed in the Hebrew calendar, a lunisolar calendar that adds a thirteenth month in 7 of every 19 years, so they move by up to a month against the Gregorian one. The tool reads the Hebrew date from the calendar data built into your browser and lists each holiday on the Gregorian day it falls on; it begins at sundown the evening before. Rosh Hashanah 2027 is Saturday, October 2, 2027, so it starts on the evening of October 1, 2027. Passover and Shavuot are listed with the days kept outside Israel.

Equinoxes and solstices

Each season starts at one moment, when the Sun crosses the equator or is farthest from it. The tool takes that moment from the US Naval Observatory's table and dates it on the US Eastern clock, with the UTC time beside it, so a September equinox at 8:00 PM Eastern Time on September 22 is September 23 in Europe.

Federal holidays on a weekend

A federal holiday on a Saturday is observed on the Friday before, and one on a Sunday on the Monday after. The tool lists the holiday on its own date with the observed day beside it, and the observed day again under its own date, the day federal offices are closed.

Find a holiday's date instead

This tool goes from a date to its holidays. To go from a year to its holidays, the US federal holidays tool lists the 11 holidays of any year, and the printable calendar marks them on every month. To count the days until one, try the Christmas countdown or the day countdown.

Frequently asked questions

How do I find out what holiday is on a date?: Pick the date: the tool lists every holiday and observance on it, from federal holidays to UN international days, each with its kind. It opens on today, so it also answers what holiday is today.
Which holidays does the tool list?: The US federal holidays and their observed days; a selection of the national observances in Title 36 of the US Code, such as Flag Day and Patriot Day; days kept on a fixed date by custom, such as Valentine's Day and Halloween; Tax Day and Election Day; Easter and the days counted from it, and Orthodox Easter; the main Jewish holidays; the equinoxes, solstices and daylight saving time changes; and the UN international days.
Why isn't National Pizza Day or another national food day listed?: Because no law or public body sets those dates: the "national day" lists for foods and causes come from private calendars and brands, and different lists give different days. The tool lists only days whose date comes from a rule or a public source it names.
Does the tool list state holidays or other countries' holidays?: No. It covers the US federal holidays, US observances, Easter, the Jewish holidays, the seasons and the UN days. State holidays, other countries' public holidays and holidays whose date depends on sighting the moon, such as Eid al-Fitr, are not listed.
When do Jewish holidays start?: At sundown on the evening before the date shown, because a day in the Hebrew calendar starts at sunset. Rosh Hashanah 2027, 1 Tishrei, falls on Saturday, October 2, 2027, so it begins on the evening of October 1, 2027.
Why does Easter move every year?: Because it follows the moon: Easter Sunday is the first Sunday after the church's full moon on or after March 21, so it falls between March 22 and April 25. It is March 28, 2027, and April 16, 2028 the year after. Good Friday is two days earlier and Ash Wednesday 46 days earlier.
Why is the September equinox on September 22 in some places and September 23 in others?: Because it is a single moment, and the date depends on the clock you read it on. In 2026 it came at 8:05 PM Eastern Time on September 22, which was already September 23 in UTC. The tool dates the seasons on the US Eastern clock and gives the UTC time beside them.
Are UN international days public holidays?: No. An international day marks a cause the UN wants to draw attention to, such as World Health Day on April 7; schools and offices stay open. No country is required to give a day off for one.
Is a federal holiday on a weekend moved?: For federal employees, yes: a holiday on a Saturday is observed on the Friday before, and one on a Sunday on the Monday after. The tool shows the holiday on its own date with the observed day beside it, and lists the observed day under its own date too.
Can I share the holidays of a date?: Yes. Copy the link under the result: it carries the date, so whoever opens it sees the same holidays.
