Calendar guide
Switzerland weekly calendar: week 1, 2026
A Monday-to-Sunday planning view
This weekly calendar follows ISO 8601 and therefore begins on Monday. The seven-day layout keeps working days and the weekend in one sequence, which helps with shift planning, appointments, travel and family coordination.
An ISO week can overlap two months or even two calendar years. The week-year and week number, not the month containing most days, determine the URL and heading. This keeps week references stable in international schedules.
Holidays and school breaks during the week
The week contains at least one stored public holiday, school-holiday period or primary Moon phase. Public and school holidays remain separate and regional scope is displayed where available.
A holiday on Monday or Friday can extend a weekend, while a Tuesday or Thursday can make a bridge day relevant. Whether a person is actually free depends on the applicable region and individual working schedule.
Compare daylight across the week
Daily sunrise, sunset and daylight values refer to the named reference location. Showing all seven days makes the gradual seasonal change visible without implying that the values apply to every place in Switzerland.
Solar values support ordinary planning but do not account for a local horizon, buildings, elevation or weather. Binding deadlines should be verified independently.
FAQ
Frequently asked questions about the weekly calendar
When does ISO week 1 begin and end?
It begins on December 29, 2025 and ends on January 4, 2026.
Why can an ISO week include two years?
ISO week 1 is the week containing the first Thursday of the year, so boundary weeks can include dates from a neighbouring year.
Does the weekly calendar include regional holidays?
Yes, when stored. Each regional date retains its scope.
Are sunrise and sunset the same throughout the country?
No. Displayed times apply only to the named reference location.
