description: "Hugo 0.87.0 brings time zone support, localized time and dates and numbers backed by CLDR, and more."
categories: ["Releases"]
---

Hugo `0.87` brings two long sought-after features: Default time zone support (per language if needed) for dates without zone offset or location info, and localized time and dates and numbers (backed by [CLDR](https://en.wikipedia.org/wiki/Common_Locale_Data_Repository)).

For more information, see:

* The [time zone config](https://gohugo.io/getting-started/configuration/#timezone) documentation.
* The [time.Format](https://gohugo.io/functions/dateformat/) documentation. This function will now give you localized dates (with weekdays and months in the current language). It supports all of Go's layout syntax, but also some predefined constants, e.g. `{{ .Date | time.Format ":date_long" }}`.
* A set of new [localized number formatting ](https://gohugo.io/functions/lang/) functions.

Also in this release, we have switched to using [go-toml](https://github.com/pelletier/go-toml) for all things TOML in Hugo. A big thanks to [@pelletier](https://github.com/pelletier) for his work on the `v2` version. It's both faster than what we had and [TOML v1.0.0](https://toml.io/en/v1.0.0) compliant.

This release represents **40 contributions by 4 contributors** to the main Hugo code base.[@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@dependabot[bot]](https://github.com/apps/dependabot), [@digitalcraftsman](https://github.com/digitalcraftsman), and [@jmooring](https://github.com/jmooring) for their ongoing contributions.

Many have also been busy writing and fixing the documentation in [hugoDocs](https://github.com/gohugoio/hugoDocs),
which has received **1 contributions by 1 contributors**.

Hugo now has:

* 53261+ [stars](https://github.com/gohugoio/hugo/stargazers)
* 430+ [contributors](https://github.com/gohugoio/hugo/graphs/contributors)
* 395+ [themes](http://themes.gohugo.io/)
