Blank = today
How to count the days until a date
Subtract the dates
Days until = target date − today. From 4 September to 25 December is 112 days.
Decide about the end day
"Days until" normally excludes the day itself. If you want to include it (a countdown that hits 1 on the day), pick "Yes" above.
Turn it into weeks
112 days ÷ 7 = 16 weeks exactly. 100 days is 14 weeks and 2 days.
Questions people ask
Does "days until" include today?
No. It counts the full days between now and the date, so the day before the event shows 1. Switch "Count the end date" to Yes if you want the event day itself included (it only applies to dates that have not passed).
What if the date has already passed this year?
The calculator jumps to next year’s date automatically for the preset pages. For a custom date that has passed, it shows how many days ago it was.
How do I count business days until a date?
The Business days tile skips Saturdays and Sundays between today and the date. It does not know public holidays.
Which time zone does it use?
Your device’s local date, so the count changes at midnight where you are.
