How to count the days until a date
The count is the number of midnights between today and the target date. The calculator converts both dates to a whole-day number and subtracts, so time zones and daylight-saving changes cannot shift the answer. Today does not count, but the target date does: from Monday to Friday of the same week is 4 days.
Worked example, January 1 to March 15 in a non-leap year: January has 31 days and February has 28, so January 1 to March 1 is 31 + 28 = 59 days. Add the 14 more days to reach March 15 and the total is 73 days. Dividing by 7 gives 10 weeks with 3 days left over, and the total hours are 73 × 24 = 1,752.
Months are counted on the calendar, not as a fixed 30 days. The calculator steps forward one calendar month at a time, so January 1 to March 1 is exactly 2 months, and the remaining 14 days are reported separately: 2 months and 14 days. If the start date is the 31st and the next month is shorter, the step lands on the last day of that month.
Frequently asked questions
Does the count include today?
No. The result is the number of full days from today until the date you pick, so tomorrow shows as 1 day and a date later today shows as 0 days. If you want to count today as well, add 1 to the total.
Why isn't the month count just the days divided by 30?
Months are between 28 and 31 days long, so dividing by 30 drifts off the calendar. The calculator advances one real calendar month at a time and reports the leftover days, which matches how people read dates like 'two months from now'.
Does the calculator handle leap years and daylight saving time?
Yes. The date math is done in whole calendar days using your device's calendar, so February 29 is counted in leap years and the hour lost or gained at a daylight-saving change never alters the day count.
