Calculate the Number of Days

Calculator for the number of days between one date and another. Please enter start and end date, the number of days between will be calculated. If the start date is taken into account, then e.g. today and tomorrow are two days. If not, then from today to tomorrow it is one day. Start or End date today enters the current date into the according line. If the end date is before the start date, the number of days is negative.
The number of days is an exact value. Therefore the number of months or years can't be calculated here, because those have alternating lengths.
