The current week number, following the Swedish standard.
Right now it is week 43 (Oct 19 - Oct 25, 2026). Nollan.se shows the week number automatically at the top of the dashboard, together with the date, weather and days until payday.
Sweden – like the rest of Europe – numbers weeks according to the international standard ISO 8601. Three rules follow from it:
Because week 1 is anchored to the first Thursday, the last days of December can belong to week 1 of the next year, and the first days of January can belong to week 52 or 53 of the previous year. That is why a calendar might show "week 1" on December 30th – it is not a mistake, it is the rule doing its job.
The rare week 53 happens in years that either start on a Thursday, or are leap years that start on a Wednesday.
One subtle point: the ISO week-year can differ from the ordinary calendar year by a day or two around New Year. That is why Nollan shows the ISO year next to the week number – so week 1 and its year always line up correctly.
Week numbers are used constantly in Swedish working life and schools: for planning, holidays, deliveries and meetings ("let's take it in week 34"). Having the current number one glance away saves you from counting.
It is week 43 (Oct 19 - Oct 25, 2026). Sweden follows the ISO 8601 standard, where the week starts on Monday and ends on Sunday.
In Sweden and the rest of Europe the week starts on Monday. That differs from the United States, where Sunday is often treated as the first day of the week – which is why some calendars and apps show a different week number.
Week 1 is the week containing the year's first Thursday – equivalently, the week that contains January 4th. So week 1 is the first week with the majority of its days in the new year.
A year has 52 or 53 weeks. The rare week 53 happens in years that start on a Thursday, or leap years that start on a Wednesday. That is also why a calendar can show "week 1" already on December 30th – it is the rule working correctly, not a bug.
