tkcalendar
Calendar and DateEntry widgets for Tkinter
Decision gist · record as of 2026-08-14
Yes, if you are building a Tkinter desktop application and need calendar or date-entry widgets. The package is stable and has low install friction. However, be aware that it is dormant—no active maintenance since 2019—so do not rely on it for bug fixes or compatibility with future Python or tkinter versions. Suitable for legacy or internal tools; less suitable for new production applications that require ongoing support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires tkinter, which is included in Python distributions for Windows but must be installed separately on Linux (e.g., python3-tk package).
- Low install friction with a single runtime dependency (babel).
- Maintenance is dormant—last release was 2019-12-28 and last commit 2024-01-24, so expect no active bug fixes or feature development.

What it is and what it does
tkcalendar provides two Tkinter widgets: a Calendar widget for displaying and selecting dates, and a DateEntry widget that combines a text field with a dropdown calendar. The Calendar widget supports event display with custom colors and tooltips, locale-aware formatting (e.g., 'fr_FR', 'en_US'), and customizable appearance through color and font options. It depends on babel for locale and date formatting.
The package is production-stable but dormant—no releases since 2019 and no active development. It is suitable for desktop applications that need date selection UI but should not be expected to receive updates for new Python versions or tkinter changes.
Use it for
- Add a date picker to a Tkinter desktop application without building custom calendar UI.
- Display events on specific dates with color coding and tooltips in a calendar view.
- Support multiple locales and date formats in a Tkinter GUI application.
- Provide a DateEntry widget as a drop-in replacement for manual date input fields.
- Build a simple scheduling or event management interface with visual date selection.
