About

I created free tool longvacation.eu, first as something to try out new Copilot abilities. Later found out there are projects like holiday-optimizer.com that are solving similar issue, so I tried to differentiate.

  • Longvacation supports adding your partner calendar (just one for now, but I plan to add multiple in the future)

  • Longvacation contains multiple sources of holidays data - so countries like India (with regions) or Indonesia are included

  • Shuffle mechanism - algorithm is non-deterministic so if you are not happy with the results, you can shuffle days around

  • Rich calendar edits

  • Monthly caps

  • Never-vacation

  • Locked vacation days (not touched by shuffle algorithm)

It's my first public project so I'm still learning how to promote it - currently I have around 3k visits monthly promoting it on X and LinkedIn

I recently open-sourced the code as well, so issues and bug reports are welcome 🙂 https://github.com/Duzij/VacationOptimizer
