How it counts
years = complete years from start to enda year ticks over on the same month and day
- start date
- the earlier date
- end date
- the later date
- years
- complete years between them
This is how age and anniversaries are counted: the year increments only when the date comes round, so a day short still counts as the lower year.
Frequently asked questions
How do you count years between two dates?
By complete years: the count rises only when the same month and day come round, like a birthday.
Does a day short still count as a full year?
No. A day before the anniversary it is still the lower number of years.
Does it show the leftover?
Yes, the extra beyond the last full year appears as months and total days.
Are leap years counted?
Yes, the calendar handles them.
