De ce există WorkDaten
WorkDaten started in early 2025 as a private spreadsheet. I was working as a freelance software engineer based in Austria, taking on client work across Germany, the Netherlands, France and Italy, and I kept needing the same answers over and over: how many working days does this quarter contain in this country, when is the next public holiday in that one, what is the current Blue Card salary threshold this year, and how exactly do I invoice a German B2B client from Austria with reverse-charge VAT?
Every time I tried to find one of these answers I ended up bouncing between four government websites in three languages, a couple of expat forums of doubtful freshness and a handful of accountants' blogs that contradicted each other. I spent more hours triangulating data than I spent writing client code. After three months of this I started keeping a single private document, one tab per country, with the data and the source URLs.
By the middle of 2025 the spreadsheet had become useful enough that I rebuilt it as a small website for my own bookmarks. Friends and other freelancers asked for access. By late 2025 it became clear the site could be useful to anyone trying to plan working life across European borders — payroll teams scheduling quarter-end, HR planning leave, freelancers invoicing across countries, families thinking about a move. So I rebuilt it again properly, in twenty-five languages, and put it online.
