Opening and closing times on Ascension Day and Whit Sunday and Monday

11 May 2023

On Thursday 18 May (Ascension Day), Friday 19 May (compulsory closure day) and Sunday 28 and Monday 29 May (Whit Sunday and Monday) most Leiden University premises are closed. You have these days off, without having to take leave. The number of hours that you normally would have worked on Friday 19 May are automatically deducted from your vacation credit. You don't have to do anything for this.

Access to buildings

If you need to work at the University during the holiday? Ask the reception if the building is open.


On 18, 19, 28 and 29 May, the University Library (UB) will be open. The UB will also be open on Pentecost Sunday and Monday. All other UB library locations will be closed. Please find the exact days and hours for each library location on the opening hours page.
