Add Days to a Date (Calendar Days)
Pick a start date and enter how many calendar days to add. The result is the new date on the normal calendar (Saturdays, Sundays, and public holidays all count). This page counts calendar days only, not Swedish bank days or business days.
How to use
Set Start date, enter Days to add as a whole number, and read the result date shown below. There is no toggle for workdays: every day in the range counts.
Example
Start 1 May 2026 and add 45 calendar days gives 15 June 2026. If your contract says "30 days" without mentioning bank days, that usually means calendar days like this tool.
Tips
For payment terms that say "bank days" or "business days", use the Working days calculator instead. Leap years and different month lengths are handled by the browser date logic.
