Hey!
I found out that Steam announces their next sales almost a year in advance. After discovering this, I started looking for a service that allows me to see the next steam sales right in my calendar. However, I couldn't find anything, so I quickly spun up a solution of my own.
It's basically just a Rust project that generates a '.ics' file from the latest information (manually entered, as I couldn't find an API for this). The repository also hosts a workflow that automatically builds the file after an update.
You can add this to your own calendar using the following URL: [steam_sales.ics](https://github.com/silvasch/steam_sales_calendar/releases/latest/download/steam_sales.ics).
Hope someone finds this useful.
That is the website where I first found about this, but I was disappointed when I couldn’t find a calendar or rss feed for it.
