Why

I just wanted to do a calendar thingy one evening. A single month, a few reminders, 80 column width (more or less).

Note: The included caldates file contains a full year of sample events (2025). Simply edit or replace with your own events!

Testimonial

"Zero tracking. Zero syncing. Zero features. I’ll never use it. It’s like the dev ran out of time."
