In similar vein: my local recycling collection is different from week to week (i.e. paper one week, plastic the next, etc). It's supposed to be on a fixed yearly schedule, but during COVID lockdowns the schedule changed dramatically, often day by day. There is a website that will tell you the most recent plan, but you can't just bookmark it - every time you have to specify the address and the date, which is annoying.

So I built a scraping script in python that runs once a day and sends me an email the evening before a collection is due, telling me what I should place outside that day. It's been working great for three years now, with zero maintenance.

I considered turning it into a public service, but i don't want any pressure from neighbors when things eventually break (as they will, inevitably, sooner or later). And really this should be a basic feature offered by the local authority website, so I hope they'll implement it one day on their own.
