How many days are there between two dates? Enter your start and end date and this calculator counts the days between them instantly, right in your browser. The total number of days is shown first, with weeks and a years/months/days breakdown underneath. Choose inclusive counting if you need both the start and end day included — useful for counting how many days you have until a deadline, how long a project ran, or how many days old something is. The count is exact: it uses leap-year-correct UTC math, so February 29 and month-length differences are handled precisely. Nothing is uploaded and there are no ads slowing down the answer.
