How to use the three modes
Whichever mode you pick, the flow is short: choose dates, read the answer, copy it. Below we walk through the days between, workdays, and countdown modes one step at a time.
Days Between mode
- Pick the start date
Tap the first date field and pick the day you want to count from.
- Pick the end date
Tap the second date field for the end day. Desktop shows the answer instantly; on mobile, tap "Calculate".
- Read the big number
The main number is the gap in days, and the "N days inclusive" line tells you the version that counts both ends.
- Copy the result
Tap "Copy result" for a plain sentence (e.g. "2026/02/04 to 2026/06/11 is 128 days apart") you can paste anywhere.
Workdays mode (weekends excluded)
- Switch to "Workdays"
Tap "Workdays" in the mode row; the signature underline turns amber to remind you that you're counting working days.
- Pick the start and end dates
Pick the start and end day as usual; the tool automatically removes the Saturdays and Sundays in between.
- Check the breakdown
The main number is the count of working days, with "Total N days | Weekend N days" beneath for cross-checking.
Countdown mode (just one date)
- Switch to "Countdown"
The second date field collapses and the input becomes a single field — you only need one target date.
- Pick the target date
Pick the day you're waiting for, and the main number shows "N days left" (green) or "N days ago" (slate).
