When working at Booking.com, Paul created a new calendar for their partners. It took him about 6 months. Months? Yes, months. Creating a calendar that works correctly all across the world for 42 different languages and even more locales, is not something that you do in a week.
In this talk, Paul will show you the weird things he learned. From Brazilian Summer Time to Slovakian (or was it Slovenian?) date formatting. And how to avoid the many (many!) mistakes he made.
