About
What the Date Difference Calculator does
One decision affects the answer: whether both endpoints are counted. The gap between the 1st and the 8th is seven days if you count the difference, or eight if you count both days inclusively. Contracts and notice periods often specify inclusive counting, so check which the situation requires.
