Calendr

Calendr provides a compact calendar interface that lives in the macOS menu bar, giving users quick visual access to the current date and upcoming events without opening a separate application. It displays the current day, month, and year, and can show multiple time‑zones side by side using a simple formatting syntax, making it useful for people who coordinate across regions. The app also supports a custom URL scheme that allows dates to be opened directly from the browser or other tools, with limited relative‑date handling such as “today” or “tomorrow”.

The software includes a built‑in blacklist editor for suppressing unwanted map or weather information in the menu bar. Advanced users can extend this filtering with regular expressions via a system defaults command, enabling fine‑grained control over which location data appears. These hidden features are configurable through the settings pane.

Targeted at macOS users who prefer a lightweight, always‑available calendar, Calendr is distributed as a stable, core‑only binary and can be installed via Homebrew cask or direct download. It is maintained with automated unit tests and error monitoring, and the developer encourages community support through contributions and optional donations.
