How to handle date change due to timezone?

Question

Django

On the front there is a date picker control. js doesn't have a date-only type, and it returns a Date including the tyzone, the date is non-empty, and the time is 00:00.
When the time arrives at the server and is parsed into a pure date object, then yesterday's date is stored in the database due to UTC.

What to do?
Do you need to make your own type to store only the date in js?
Add 12 hours on the server to avoid changing the date from the time zone?

You need to store a timezone on the client, but you can convert it like this https://stackoverflow.com/questions/10087819/conve...
In general, it's better to work everywhere in utc, and show with conversion to local.
