It tries to schedule PTO around holidays so that you get the most consecutive time off while spending as few days as possible.

You can set some constraints, customize the holidays and define mandatory vacation days (in case your company mandates them).

If you try for 2025, you should see results for the rest of the year. If there are unscheduled days, it's because there isn't a particularly good period to take them off. (I should make this clearer in the site, to be honest).

Let me know if you have any questions or comments and hope you get value out of it!
