CalendarKit – A Windows-like taskbar calendar for macOS/Chrome — with a built-in calculator too

Hey All,

I switched from Windows to Mac last year and the one thing I genuinely missed was the taskbar calendar.

On Windows — click the clock, full calendar opens, check any month, close it, back to work. Seamless.

On Mac — click the clock, see today's date. That's it. Want to check December? Open Calendar app, switch screens, lose your focus, navigate back. Every. Single. Time.

Same problem with calculator — on Windows it's always within reach, on Mac you're opening a whole separate app.

So I built CalendarKit — a Chrome extension that fixes both.

What it does:

  • Full Google Calendar in a popup — navigate any month without leaving your screen

  • Built-in Calculator with persistent history

  • Dark theme, minimal UI

  • Zero data collection — everything stays local

  • Set your default tab (Calendar or Calculator)

It's completely free and open source.

Chrome Web Store listing coming soon — for now you can install it manually in developer mode (takes 30 seconds, instructions in the README).

Would love feedback — especially if there's a utility you wish was always one click away. I'm planning to add World Clock, Quick Notes, and Unit Converter next based on community feedback.
