Show HN: Made a system tray calendar that syncs all your calendars (calendar0.app)

Hey HN!

I'm the creator of Calendar0, a menubar calendar for MacOS and Windows that I've been working on for the past few months.

The app is designed to make calendar management actually accessible without opening a browser every time you need to check your schedule.

One of Calendar0's main goals is to eliminate the constant context-switching between multiple calendar accounts and providers.

The latest update finally adds Apple Calendar support alongside Google and Microsoft 365, so you can now see all your calendars in a single unified view.

I also just shipped bulk operations: you can add buffers to multiple back-to-back meetings in seconds instead of manually editing each one.

Would love to have your feedback!
