I know this isn't any kind of surprise, and yet, well...
Programming aside, where I live in Southern Europe we have a tradition according to which leap years bring bad luck. After 2020, I don't know what to expect... nuclear apocalypse maybe?
I'm not worried about my code, I'm (very slightly) worried about all the date libraries I used because I didn't want code that shit again for the billionth time.
Your comment made me go look at the source for moment.js. It has "leap" 13 times and the code looks correct. I assume they test stuff like this.
Yeah, I'm generally using the common data/time libraries in most (if not all) languages and I'm pretty sure they've all been through more than 1 leap year at this point. I just never 100% trust the code I don't control - 99.9% maybe, but never 100.
We found an use case with Page duty and it's ical feed already...
