Calendar integration (ICS)

Use this tool to generate a custom URL that can be added to your calendar.
Once added, it will automatically display all upcoming SpaceX missions for which the launch time is known precisely.

Make sure to add the calendar feed as an external (subscribed) calendar using the URL, do not import the events manually.
Google Calendar, Apple Calendar

Disclaimer: Certain calendar clients will take a long time (+24h) before changes to events (missions) are reflected in the calendar.
For the most recent info, check the mission in the app.
