A calendar that does the counting for you
The calendar above opens on the current year, with today circled. Holidays for the country you choose are underlined, and the narrow first column gives the week number of each row. Tap a month to open it in large, with the name of every holiday and observance written in the day. The arrows move by one year (or by one month in the month view), and tapping the year opens a wheel that goes from 1900 to 2100.
The country is set from your language (the United States on this page) and remembered once you change it. Thirteen countries are available: the United States, Canada, the United Kingdom, Mexico, Brazil, France, Belgium, Switzerland, Germany, Austria, Spain, Italy and Portugal.
Print a yearly calendar on one page
Tap Print, or press Ctrl+P (Cmd+P on a Mac). The page switches to a print layout made for paper: white background, black text, the 12 months in three columns and the list of holidays at the bottom. It fits on one US Letter or A4 sheet in portrait. If your printer adds margins, choose “Fit to page” in the print dialog. In the month view, Print gives you a single large month with room to write in each day, handy for a fridge or a shared office board.
US federal holidays: the rules
The United States has 11 federal holidays. Federal offices close, and most banks and many employers follow them. Most are tied to a weekday rather than a date, which is why they move every year.
| Holiday | Rule |
|---|---|
| New Year’s Day | January 1 |
| Martin Luther King Jr. Day | Third Monday in January |
| Washington’s Birthday (Presidents’ Day) | Third Monday in February |
| Memorial Day | Last Monday in May |
| Juneteenth | June 19 |
| Independence Day | July 4 |
| Labor Day | First Monday in September |
| Columbus Day | Second Monday in October |
| Veterans Day | November 11 |
| Thanksgiving Day | Fourth Thursday in November |
| Christmas Day | December 25 |
When a fixed-date holiday falls on a Saturday, federal workers get the Friday before; on a Sunday, the Monday after. That is why December 31, 2027 is a federal day off: New Year’s Day 2028 is a Saturday. The calendar underlines these observed days too. Observances such as Valentine’s Day, Mother’s Day or Halloween appear in the month view but are not underlined, since they are not days off. The full lists, country by country, are on the public holidays page.
Week numbers explained
The week numbers follow the international standard ISO 8601, used in business, logistics and most of Europe. A week runs from Monday to Sunday, and week 1 is the week that contains the first Thursday of the year, which is also the week that contains January 4. A year therefore has 52 or 53 weeks: 2026 has 53, because it starts on a Thursday, while 2027 and 2028 have 52.
US calendars start the week on Sunday, so each row here runs from Sunday to Saturday, and the number shown is the ISO week of the Monday in that row. Six of the seven days belong to that week. To look up any date, use the week number calculator, or see every week of the year on the 2027 week numbers page.
Leap years and repeating calendars
A year is a leap year if it can be divided by 4, except century years, which must be divisible by 400: 2000 was a leap year, 2100 will not be. The next February 29 falls in 2028. Because the weekdays shift by one day each year (two after a leap year), calendars repeat: the 2027 calendar is identical to 2021 and will come back in 2038, and the 2026 calendar is the same as 2015 and 2037. An old printed calendar can be reused, as long as you check the holidays that depend on Easter.
Seasons, moon and clock changes
The month and year pages also give the dates that shape daily life beyond holidays. Astronomical seasons start at the equinoxes and solstices: in 2027, spring begins on March 20, summer on June 21, fall on September 23 and winter on December 21, Eastern Time. Clocks spring forward on March 14, 2027 and fall back on November 7. Each month lists the new moon, first quarter, full moon and last quarter with their times, so you can plan a night walk, a fishing trip or a photo of the full moon. All these figures are calculated, not copied: the seasons with Jean Meeus’s astronomical formulas, the holidays from each country’s rules.
Month pages and year pages
Each year has its own page with the holidays, the seasons, the clock changes and the full moons: 2026 calendar, 2027 calendar and 2028 calendar. Every month of 2026 and 2027 has a page too, with working days, long weekends, moon phases and key dates, from January 2026 to December 2027. Next up: December 2026 and January 2027.
To count the days between two dates, use the date calculator; to find the weekday of any date, the day of the week finder; and to know when the clocks change, see daylight saving time.
