Itsycal
Itsycal is a small macOS menu bar calendar that shows dates, events, and quick calendar access with tight integration with Apple's Calendar app.
What is Itsycal?
Itsycal is a lightweight calendar utility for macOS published by Sanjay Madan through Mowglii. It lives in the menu bar and provides a compact monthly calendar, upcoming events, and quick date access without opening the full Calendar app. The app integrates with Apple's Calendar data, can create and display events, and supports actions such as joining virtual meetings from calendar entries. It also offers keyboard navigation, configurable date and time display, ISO week numbers, Dark Mode support, and options to show more than one month at a time. Mac users commonly encounter it as a replacement or companion for the standard menu bar clock when they want faster access to schedules. Because it is a small standalone utility rather than a system component, its files are usually only needed if you actively use the app.

Safety overview
Status: Safe
Itsycal is a legitimate macOS utility from Mowglii/Sanjay Madan and is generally low risk. It reads calendar information when you grant Calendar access, so the main privacy consideration is that it can display your event titles, times, and related details in the menu bar interface.
Recommendation: Keep it if you use a menu bar calendar or rely on quick event access. If you do not use it, removing the app is usually reasonable because it is not required for macOS itself.
