What stands out in 2027

2027 begins on a Friday and ends on a Friday. It is a common year of 365 days; the next leap year is 2028, the very next year. It has 52 ISO weeks. Week 1 begins on Monday, January 4. New Year's Day therefore still belongs to week 53 of 2026.

Counting Monday through Friday, 2027 has 261 weekdays. Twelve of them are observed US federal holidays, which leaves 249 federal working days. Juneteenth National Independence Day falls on a Saturday, so the federal holiday is observed on Friday, June 18. Independence Day falls on a Sunday, so the federal holiday is observed on Monday, July 5. Christmas Day falls on a Saturday, so the federal holiday is observed on Friday, December 24. January 1, 2028 is a Saturday, so its holiday is observed on Friday, December 31, 2027, giving 2027 a twelfth holiday date. Thanksgiving is on November 25.

Western (Gregorian) Easter is on Sunday, March 28, an early date, since it lands in March. There are twelve full moons and thirteen new moons in 2027 by UTC date, one full moon per month, so there is no calendar-month blue moon. Friday the 13th occurs once, in August.

In the United States, clocks go forward on Sunday, March 14 and back on Sunday, November 7. The United Kingdom and the European Union change on Sunday, March 28 and Sunday, October 31. Between those dates the usual gap between New York and London shrinks by an hour: for 14 days in spring and 7 days in autumn the two cities are four hours apart instead of five, which is worth checking before booking transatlantic calls.

Reading the week numbers

The calendar uses ISO 8601 weeks, the convention common in Europe and in business reporting: weeks start on Monday, and week 1 is the week that contains the year's first Thursday (equivalently, the week containing January 4). A year therefore has 52 or 53 ISO weeks, and the first or last few days of January and December can belong to a neighboring week-year. In the United States, printed calendars usually start the week on Sunday and count January 1 as part of week 1, so a US week number can differ from the ISO one by a week. When a schedule says "week 14", confirm which system it means; the ISO vs US week comparison shows both side by side.

Printing the calendar

Use the print button or your browser's print command. The printed version leaves out the site header, navigation, and the reference tables, keeps each month whole, and lays the year out three months to a row; portrait orientation fits it on two pages. Holiday and moon symbols print in black, so the key above still applies on a monochrome printer.

2027 calendar questions

How many weeks are in 2027?

2027 has 52 ISO 8601 weeks. Week 1 begins on Monday, January 4, 2027, and week 52 ends on Sunday, January 2, 2028. Counted as plain seven-day blocks, 2027 is 52 weeks and 1 day.

Is 2027 a leap year?

No. 2027 is not divisible by 4, so it has 365 days and February ends on the 28th. The next leap year is 2028.

What day does Christmas fall on in 2027?

Christmas Day, December 25, 2027, falls on a Saturday. The US federal holiday is observed on Friday, December 24.
