📅 Date & Age

Calculations involving dates come up more often than they seem. Finding out how many days until an event, exactly how many days, weeks or months lie between two dates, or a baby's age in days can be tedious by hand, because the number of days in months and leap years complicate things.

The tools in this category take all these details into account for you. You can perform operations such as age calculation, the difference between two dates and adding days to a date in seconds by selecting the dates. Since the results take leap years and varying month lengths into account, there's no need to count one by one on a calendar.
