This is a duplicate of #836.

There are a few options for fixing it:

1. Edit your IANA tzdata/northamercia file: change "April" to "Apr" on one (non comment) line (line 2634), or
2. Upgrade this library to the tip-of-master where parsing has been changed to accept "April", or
3. Manually stick with 2024a, or
4. Talk the IANA maintainer (@eggert) into releasing 2024c which has already changed "April" to "Apr", but not yet been released.

Any one or more of these options will fix your issue, and be forward compatible.
