Copy the desired calendar link from Byga and then add it to a web based Google calendar, as follows:
- On the Byga web page for a calendar, choose "Copy Subscription Link." This puts the URL in your clipboard.
- In Google calendar on the web, click the "+" (next to "Add a friend's calendar") and then "From URL".
- Paste the copied link in there, and click "Add Calendar."
Note: to subscribe in google, you must use the web based google calendar as it is not possible to subscribe to a calendar in the Google calendar mobile app.
You can follow a similar process for non-Google calendars. Please follow the instructions in your calendar app.
