Poster to Calendar
Poster to Calendar turns a photo of an event poster, flyer, or screenshot into a ready-to-save calendar event, with the title, date, time, and place filled in.
Last updated October 27, 2026
How to use it
- Open Poster to Calendar and snap or upload the poster.
- Bum Bum reads it and builds the event, or several, if the poster lists a lineup.
- Check every detail and fix anything it misread.
- Save with one tap as a calendar file, or add it straight to Google Calendar.
Good to know
- One poster read uses one action, however many events it holds, up to six.
- Screenshots of digital posters work just as well as photos of paper ones.
- Relative dates get resolved for you: a poster that says Friday means the coming Friday.
- No poster handy? The sample poster on the page drops three editable events in for free, so you can see the whole flow first.
- If a photo holds no event at all (a pet, a selfie, a menu), Bum Bum says so instead of guessing. It only reads posters and flyers.
Your data
Your photo is sent to the reader, read, and discarded. It is never stored.
Tips
- Crooked photo, straighten it first with Image Cropper, or just retake it square-on. Dates read far more reliably head-on.
- Always eyeball the year on New Year's-adjacent posters. Humans get that wrong too.
