  -Now choose the library that pickers will use to work with date. We are providing interfaces for [moment](https://momentjs.com/), [luxon](https://moment.github.io/luxon/), [dayjs](https://github.com/iamkun/dayjs) and [date-fns v2](https://date-fns.org/). If you are not using moment in the project (or dont have it in the bundle already) we suggest using date-fns or luxon, because they are much lighter and will be correctly tree-shaked from the bundle. Note, that we are fully relying on [date-io](https://github.com/mui-org/date-io) for supporting different libraries.
