Original Summary

I needed to find overlapping working hours across regions — usually two places, sometimes three to five. So I built this. overlaphours.com Type in the places. It shows the window where everyone's in business hours, and the wider one where everyone's at least awake. With 3+ places it ranks the best slots by who gets inconvenienced least. Nothing to install, no signup, no cookies. One HTML file, about 50KB. Things I got wrong at first: the weekend isn't Saturday–Sunday everywhere. Riyadh and London only share Monday to Thursday. The UAE moved to Sat–Sun in 2022, so Dubai works Fridays. Feedback welcome.   submitted by   /u/Embarrassed-Resist18 [link]   [comments]
