The Core Difference

Your calendar shouldn’t be a silo.

Your calendar shouldn’t be a silo.

Keep using the calendars you already use.

Your team already uses Google Calendar, Outlook or iCloud. Asking them to switch means people end up keeping two calendars, or ignoring one.

Atlas Calendar works alongside them instead. It syncs both ways, so an event created in Atlas shows up in Google, and an invite accepted in Outlook shows up in Atlas. Your team keeps using what they already use.

Using Apple Calendar or Thunderbird? Atlas runs a native CalDAV server, so you add it like any other CalDAV account. Nothing else to set up.
