# Dates and Timezones

When working with dates, it's important to consider the timezone of the client compared to that of the database server. This library allows you to handle dates using `Date` or `dayjs` on the client side, serialize them, and send them to the backend, where you can choose the appropriate timezone for formatting.

Here's an example of using different timezones with MySQL:

<CodePreview
  code={`const us = new MySQLFlavor({timezone:'America/Chicago'});\nconst eu = new MySQLFlavor({timezone:'Europe/Prague'});\nconst c = Cond.between('date',[dayjs().startOf('month'),dayjs().endOf('day')]);\nreturn { us: c.toSQL(us), eu: c.toSQL(eu) };`}
/>

Dates are serialized as Unix timestamps in milliseconds. Here’s how to serialize date ranges:

<CodePreview
  code={`const c = Cond.between('date',[dayjs().startOf('month'),dayjs().endOf('day')]);\nreturn c.serialize();`}
/>
