@mertsincan - I'm trying to figure out if I'm crazy or if this bug still exists in 3.36.0. I can reproduce it on the documentation page demo...

To reproduce it:

1. Go here: https://primevue.org/calendar/
2. Select a date and time. Make the time 12:xx am. Example:

3. Click off of field to remove focus (you can click anywhere else on the page)
4. Click on the field again and select any date. When you do that, the "am" will automatically change to "pm" even though the time wasn't changed/touched:

This is still happening in 3.46.0, including on the documentation page, as described above.
