Calculate days, weeks and weekdays remaining until any chosen target date. The calculator runs entirely in your browser and pairs a focused answer with the method, assumptions and the related tools worth checking next.
Your inputs stay in this browser tab. Nothing is sent to a server to produce the result.
Review the inputs and select Calculate.
Enter a target date and the date to count from. The calculator counts the exact calendar days between the two dates and reports them as days to go, together with the target date's weekday, the whole weeks in the span and the Monday-to-Friday weekdays it contains.
The headline figure is the number of whole calendar days from the counting-from date to the target date. Whole weeks are complete seven-day blocks within that count, and the weekday figure counts each Monday to Friday in the span once.
Counting from 20 October 2026 to Christmas Day, Friday 25 December 2026, gives 66 days to go — 9 whole weeks, with 49 weekdays in the span. Edge case: a target date in the past is reported the same way but as days ago, and a target of today gives 0 days to go.
The count is in whole days, so it does not tick down hour by hour and takes no account of the time of day. Weekdays remaining treats every Monday to Friday alike — public holidays in the span are not removed.
Enter a target date and the tool counts the days, weeks and weekdays remaining. Each step below is a short action rather than a wall of explanation.

As whole calendar days between the counting-from date and the target date. Counting from 20 October 2026 to Christmas Day, 25 December 2026, gives 66 days to go, and the result also shows the target date's weekday.
It counts each Monday-to-Friday day inside the span once. The Christmas example above contains 49 weekdays, but public holidays inside the span are not removed, so it is a weekday count rather than a working-day count.
Whole weeks are the complete seven-day blocks within the day count. 66 days contains 9 whole weeks with 3 days left over, which is how the result panel presents the same span.
The count is reported the same way but as days ago instead of days to go. A target date of today gives 0 days to go.
The result is in whole days, so it changes only when the date changes, not hour by hour. It takes no account of the time of day, which keeps the figure identical whenever you check it on the same date.
