Hello @meeri.prejawa,
Thank you very much for sharing your questions in the International community.
These half days must be entered into Personio in your individual public holiday calendar. If an employee submits a leave request for 24.12. to 03.01., this will be calculated as only 4.5 vacation days, as shown in the example, since the days shown in green are not counted, or are only counted as half days.
You can do this by going to Settings > Public holidays. Create a new public holiday calendar by either duplicating and editing an existing public holiday calendar or by creating your custom holiday calendar in line with your company's internal requirements. You can then add custom public holidays to both duplicated or newly created public holiday calendars.
To have a detailed explanation on how to create a custom holiday calendar, please visit our help center article: Configuring Public Holiday Calendars and Public Holidays.
You can also visit our help center article: Configuring offices, to learn how you can add the holiday calendar to the specific office.
If you have any other question, please share it with the community. Have a great weekend!
Best regards from Madrid,
-Maria Laura
