Date and time errors

Good afternoon Joe,

I am having some issue with the calendar on most recent version.

All current events I have are shifting by 3 hours behind what they should be. So if I have en event that I created with 6:00PM-9:30PM it’s showing instead as 3:00PM-6:30PM

When adding new events there are a few issues. 1. when I select a date from the calendar view  it’s setting the month 1 ahead of what it should be, so if I select November 10, it actually sets december 10, and when I save the event, it actually saves as December 9th , even if I manually change the numbers (rather then calendar view) it still behaves like this.

My wordpress setting show UTC-4 and server time matches, in Mycalendar under support, it shows DB UTC Offset: +00:00 WP UTC Offset: -04:00

I had tested with other plugins disabled and still had the same issues.

Any ideas what the issue might be? I have all plugins up to date and running version 3.6.15 of my Calendar, WordPress version 6.8.3,
