About
Three Month Calendar (3MC) is a Mac app that shows a seamless, freely scrolling weekly calendar with no gaps between months. It drops down from the menu bar with a click or keyboard shortcut, and it can display events from your Mac's Calendar app or just a simple date view. While open, it stays on top of other windows without taking keyboard focus, so you can keep it visible while you work.
The app is highly configurable. You can choose from five sizes, pick a color scheme (including light and dark themes that follow your system setting), and set how the window behaves. Multiple calendar views let you switch between contexts such as work and personal, each with its own calendars, labels, and event markers. Hovering over a marked day shows a summary of its events, or you can switch to a click-to-view mode. The menu bar icon can also be replaced with a text or compact date display, and a global keyboard shortcut and login startup are available.
It uses the Gregorian calendar and adapts to your Mac's language, date formats, and first day of the week. 3MC is a one-time purchase of $7.99 (US) and runs on macOS 27, 26, or 15.
What's new
All release notesWhen using the textual current date as the menu bar item, instead of the icon, 3MC now correctly localizes it to your language. And when opening the calendar, it now consistently uses the pull-down animation; some people in some cases were seeing it use an alternate animation.
