Calculated from your local device time.
How ISO weeks are counted
ISO weeks start on Monday and the first week of the year is the one that contains the year's first Thursday. This keeps the numbering consistent worldwide.
Using this rule, week numbers follow the ISO-8601 standard used across Europe and work well for project planning.
Why device time matters
The displayed week uses your device clock so it respects your timezone, daylight saving offset and any manual adjustments.
- Traveling? The week automatically follows your current timezone.
- No server-side timezone assumptions are made.
- Refreshing recalculates the range with the latest local time.
Check the date span quickly
Look at the start and end dates to see which days the current week covers.
- Start is always Monday at 00:00 based on your device time.
- End is Sunday at 23:59 in the same timezone.
- Use the refresh button if your clock or timezone changes while the page is open.
