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.How many weeks are in 2022?
