15 days in weeks and months
15 days is 2 weeks and 1 day.
That's 360 hours, or 21,600 minutes.
Counting back 15 calendar days includes weekends. If you only need working days, use the business-day date shown above, which skips Saturdays and Sundays but not public holidays.
How to count it yourself
On a paper calendar, move up 2 rows from today. That covers 14 days and keeps you on today's weekday. Then count 1 more square to the left to finish the remaining 1 day.
A quick check: 15 days ago always falls 6 weekdays after today's in the weekly cycle. The full weeks cancel out, and stepping back 1 day lands on the same weekday as stepping forward 6.
