Small business owners around the world post monthly calendar images on social media — "here's when we're open, here's when we're closed."
3 min. Calendar generates these images in your browser. No account. No server. No tracking.
It now supports 11 languages with localized holidays, and 14 color themes to match your brand.
Already in use
A guesthouse in Noto, Japan — Kikyou-an — has been using 3 min. Calendar to post their monthly availability on Instagram.
Noto was hit by a magnitude 7 earthquake in 2024. The area is still recovering. Kikyou-an reopened as a small guesthouse to support the local community — and they've been getting bookings from overseas guests.
When they told us "the badge text (休, 満, etc.) is too small to read" — we made them bigger. When they said "I actually made a calendar in 3 minutes" — well, the name checks out.
