The date string is too long when week view is enabled

[SihaoLiu]

Hi! Thank you so much for creating and hosting such an amazing project. I have a tiny feature request (or maybe it is already there), which is that the date sting seems a bit too long when the week view is enabled as below:

I am wondering if there is an option that I can show a short version of month string, like "Aug" instead of "August" in the week view.

Thank you!
