The [https://wiki.gnome.org/Apps/Calendar Gnome calendar] is the desktop calendar application built into GNOME.

== Using Gnome Calendar outside of GNOME ==

To use the gnome calendar outside of gnome, you need the following lines in your configuration.nix:

<syntaxHighlight lang="nix">
{
  programs.dconf.enable = true;
  services.gnome.evolution-data-server.enable = true;
  # optional to use google/nextcloud calendar
  services.gnome.gnome-online-accounts.enable = true;
  # optional to use google/nextcloud calendar
  services.gnome.gnome-keyring.enable = true;
}
</syntaxHighlight>

External calendar such as google/nextcloud can be only added via the gnome-control-center:

<syntaxHighlight lang="console">
$ nix-shell -p gnome.gnome-control-center --run "gnome-control-center"
</syntaxHighlight>

Than add your accounts in the "Online Accounts" submenu.

To get alarm reminder you need to start the evolution-alarm-notify deamon provided the <code>gnome.evolution-data-server</code> package. When you enable <code>services.gnome.evolution-data-server.enable</code> it will add a desktop autostart entry to <code>/run/current-system/sw/etc/xdg/autostart/org.gnome.Evolution-alarm-notify.desktop</code>. If your desktop manager does not process autostart entries, you can use [https://github.com/jceb/dex dex] instead:

<syntaxHighlight lang="console">
$ dex --autostart
</syntaxHighlight>

As an alternative you can start <code>libexec/evolution-data-server/evolution-alarm-notify</code> from the <code>gnome.evolution-data-server</code> directly.
