How do I enable alarms on Google Calendar?

Google Calendar does not care about alarms in subscribed calendars. But you can set the alarms in a different way.

Step 1
After logging in to Google Calendar, take a look in the panel in the left side. If needed, open Other calendars by clicking to show the calendars. Click and select Settings.
