Bug Description

When we use view mode as dayGridMonth and dayHeaderFormat value is configured something like 'ddd, DD/MMM' or 'ddd, DD/MM' the month part is always representing January like Jan or 01. Current month is March and still the header shows January.

Here is a screenshot for your reference:

When I configured dayHeaderFormat value to include year like 'yyyy, ddd, DD/MMM', year is shown as 1970. So it seems its using min date object instead of using current date object.

Here is the screenshot:

Additionally second bug is when we navigate to previous month or next month also, this does not change the header, looks like re-rendering is not happening for headers.

This is not just with latest version, its happening with v5.x as well. Not sure how I have never noticed it so far.
