One Calendar is an API that wraps around commonly used calendars, such as Google Calendar and Microsoft Exchange, and was developed by the team behind the One Diary app.

Instead of trying to set up everything manually in a cron job, he created a short and easy-to-modify JavaScript script to keep track of events on a Google Calendar.

Google just made the lives of third-party calendar developers much easier. Rather than having to constantly poll Google Calendar servers for updates, the Calendar API now supports push notifications.

In the latest teardown for the Google Calendar app, version 5.5.9, it appears as though the app is to get snoozing reminders once again.

The lightweight SDK and API enable developers to effortlessly embed a robust scheduling system with seamless Google and Outlook calendar integration into their React applications.
