Your month. Just write on it.
OpenMonth skips the ceremony of traditional calendar apps. Click any day and start typing. Press Enter for another line. Move things when plans change. Your month stays readable no matter how busy it gets.
Nothing breaks when life gets busy
Fit Month keeps the whole month visible. Open a busy day for more room, or expand the calendar to see everything you've written.
Move things like paper
Drag entries between days, reorder your plans, check things off, and highlight what matters.
Find anything
Search everything you've written across months and years without sending your calendar anywhere.
Your calendar stays yours
OpenMonth stores your calendar locally, with manual backups and automatic recovery versions. No account required.
Put it on paper
Create polished monthly prints and PDFs in Letter or A4, portrait or landscape.
Local-first by design
Your calendar isn't our business.
OpenMonth is local-first. Your calendar entries stay on your computer during normal use. No account is required, and OpenMonth does not send your calendar content to a cloud service.
Create portable backups whenever you want, restore earlier versions locally, and keep control of your own data.
Looks good after dark, too.
Choose System, Light, or Dark. Light Mode uses a warm paper-inspired palette; Dark Mode keeps things soft and easy on the eyes.
From screen to paper without fixing anything.
Print the entire month on one page or use Expanded layout when you've written more. Save directly to PDF, choose Letter or A4, portrait or landscape, and decide whether completed items should appear.
