About the Calendar
The Gregorian calendar, used worldwide for civil purposes, was introduced by Pope Gregory XIII in 1582. It organizes a year into 12 months of varying lengths: January (31 days), February (28 or 29), March (31), April (30), May (31), June (30), July (31), August (31), September (30), October (31), November (30), and December (31). A common year has 365 days, while a leap year has 366.
Leap year rules: A year is a leap year if it is divisible by 4, except for century years, which must be divisible by 400. This means 2000 and 2400 are leap years, but 1900, 2100, and 2300 are not. The extra day is added to February, giving it 29 days instead of 28.
ISO week numbering: Under the ISO 8601 standard, weeks start on Monday and the first week of the year is the one containing the first Thursday of January. Most years have 52 ISO weeks, but years where January 1 falls on a Thursday (or Wednesday in leap years) have 53 weeks. Week numbers are shown in the left-hand column of the calendar above; click any date to see its day of the year and quarter too.
Frequently Asked Questions
2026 has 261 weekdays (Monday to Friday). 11 US federal holidays fall on weekdays, which leaves 250 working days for a US federal schedule. Your own count depends on your employer's holiday calendar and paid time off.
October 2026 has 31 days, of which 22 are weekdays and 1 is a federal holiday, leaving 21 working days.
January 1, 2027 falls on a Friday. 2026 started on a Thursday and ends on a Thursday.
2037 uses exactly the same calendar as 2026: January 1 falls on the same weekday and both are common years, so every date lands on the same day of the week. A calendar from 2026 can be reused in 2037, though holidays tied to Easter or the Chinese calendar will differ.
The next full moon is on Monday, October 26, 2026. Moon phases are marked on the calendar above with π new moon, π first quarter, π full moon and π last quarter; times are calculated astronomically and shown in your time zone.
January, March, May, July, August, October and December have 31 days. April, June, September and November have 30. February has 28 days, or 29 in a leap year. A common way to remember it is the knuckle trick: count the months across your knuckles and the gaps between them β every knuckle month has 31 days.
The calendar follows ISO 8601, the international standard, where weeks run Monday to Sunday and week numbers are counted from the week containing the year's first Thursday. Most of Europe and much of the world use this layout; US wall calendars usually start on Sunday, which is an option in the printable calendar.
