Find the difference between two dates — in years, months, days, weeks, and hours — or the difference between two times of day. Useful for age, project durations, notice periods, and countdowns.
It counts full years, then remaining months, then remaining days between the dates — and also shows the totals in days, weeks, and hours.
The difference is the span between the two dates. If you need an inclusive count (both endpoints), add one day to the total.
Yes — use the 'between two times' mode. If the end time is earlier than the start (an overnight shift), it correctly rolls over to the next day.
