Day.js is a date manipulation library that's used by Trilium, but it's also shared with both front-end and back-end scripts. For more information about the library itself, consult the official documentation.

## How to use

The `dayjs` method is provided directly in the `api` global:

    const date = api.dayjs();
    api.log(date.format("YYYY-MM-DD"));

## Plugins

Day.js uses a modular, plugin-based architecture. Generally these plugins must be imported, but this process doesn't work inside Trilium scripts due to the use of a bundler.

Since v0.100.0, the same set of plugins is available for both front-end and back-end scripts.

The following Day.js plugins are directly integrated into Trilium:

- AdvancedFormat
- Duration, since v0.100.0.
- IsBetween
- IsoWeek
- IsSameOrAfter
- IsSameOrBefore
- QuarterOfYear
- UTC

If another Day.js plugin might be needed for scripting purposes, feel free to open a feature request for it. Depending on the size of the plugin and the potential use of it inside the Trilium code base, it has a chance of being integrated.
