My town used to post our garbage pickup schedule as a photo pdf to our town's website.

They tend to change when garbage will be picked up randomly espcially near holidays, so it can be annoying and we'd end up running out in the morning when we heard the truck driving by on 'off' days

The changes always made it into the calendar at least the night before.

I wrote a horrible python abortion to grab the PDF, OCR the data, and then put it into HA so I can have HA turn a light on in my hallway the night before.

These days they make the calendar available as an iCal file so data ingest is way easier.
