Key figures
2040 is a leap year with 366 days, because February has an extra day. It begins on a Sunday and ends on a Monday, and it contains 52 ISO weeks, 261 weekdays and 52 Saturdays. Leap years follow a simple rule: divisible by four, except century years that are not divisible by 400. The shortest month is February and the longest months, at 31 days, are January, March, May, July, August, October and December. 2040 starts on Sunday, January 1, 2040 — 4,841 days from today, Wednesday, September 30, 2026. Once it begins it will have 366 days, 52 ISO weeks and 261 weekdays to plan around. Counting remaining days is the simplest way to pace a year. Divide a target — sales, savings, words written, miles run — by the days left to see the daily rate you need, or by the weekdays left if you only work Monday to Friday. The next dates worth planning around in 2040 are New Year (Sunday, January 1); Martin Luther King Jr. Day (Monday, January 16); Groundhog Day (Thursday, February 2); Chinese New Year (Sunday, February 12). The full list, with the number of days from today for each, is on the 2040 holiday calendar, and every name there links to a countdown in days, weeks or months. Quarter one runs from January 1 to March 31, quarter two ends on June 30, quarter three on September 30 and quarter four on December 31. Payroll, tax deadlines, school terms and fiscal reporting are all built on those boundaries. If you are planning across a year end, note that Monday, December 31, 2040 is the last day and Tuesday, January 1, 2041 is the first day of the next year. Today is Wednesday, September 30, 2026. That is day 273 of 365 in 2026, in ISO week 40, with 92 days to go before the year ends. The next dates people plan around are Diwali on Saturday, October 10; Columbus Day on Monday, October 12; Halloween on Saturday, October 31. The moon is a Waning Gibbous tonight, with about 81% of its face lit.
