Specify a date range

[renard]

This project is AWESOME. Now it's very easy to create calendars.

Anyway is it possible to ass a function to specify date ranges for holidays. The following is a very good example of what I am looking for:

Thanks in advance.

Edit: I just saw the period command can do the job. Meanwhile is it possible to add something to just draw a small bar like in the given picture instead of filling the whole days?

TIA

The colored bars is a good idea. Unfortunately it's not easy to implement. Sorry, I have not enough time.

@rolfn Fair enough. Meanwhile I have made small changes to achieve this goal using the following patch. This is not an one-size-fits-all but works for me. I just drop it here if someone might file it useful. Anyway if you prefer a PR let me know.

Only a short hint. You should not use absolute length like "-5pt". For vertically length use multiples of \RN@yunit and for horizontal length multiples of \RN@xunit.
