Year overview
2022 has 52 ISO weeks. Week 1 starts on Monday, January 3, 2022 because week 1 is the week that contains the first Thursday of January. The last week ends on Sunday, January 1, 2023. 2022 is a regular ISO year with 52 weeks. A 53rd week appears in roughly one ISO year out of every five or six. Months and weeks do not line up neatly, so the table lists the first and last ISO week that touches each month. January begins in week 52 and December ends in week 52. A week that straddles two months is counted in both rows. Manufacturing, retail, logistics, schools and government agencies in most of Europe and Asia plan in ISO weeks. A production run in week 32 or a report due in week 45 means the same span for everyone regardless of weekday. Using the week number avoids confusion between calendars that start weeks on Sunday and those that start on Monday. Use the numbered links to open the exact dates of any week, or type a date into the form above to find its week number. The overview stays correct for any year because it is calculated from the ISO 8601 rule instead of typed in. 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. All of these figures are recalculated when the page loads, so they always describe the day you open it, not the day the page was published. The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.How many weeks are in 2022?
