Today is Wednesday, October 28, 2026, in week 44 of 2026. The week runs from Monday, October 26 to Sunday, November 1.
How week numbers work
Week numbers follow the international standard ISO 8601: every week starts on Monday, and week 1 is the week that contains the first Thursday of the year – which is always the week with January 4 in it.
That is why the first days of January can belong to week 52 or 53 of the year before, and the last days of December to week 1 of the next year. A year has 52 or 53 weeks.
