Hey PH! 👋 I built BizCal API because I kept running into the same problem: date math involving business hours, public holidays, or multiple countries is deceptively hard to get right. The specific pain points that motivated this: - "24 business hours from Friday 3pm" is not Saturday 3pm -- it's Wednesday 3pm after crossing a weekend - US federal holidays differ from California and Texas holidays (sub-national matters for payroll) - Germany alone has 16 states with different holiday calendars -- Bavaria has 4 more public holidays than Berlin - DST transitions silently break naive datetime arithmetic BizCal handles all of it: 22 endpoints across business days, working hours, and holiday lookups for 15 countries with ~200 regional calendars. Free tier (50 req/day) covers US, UK, and AU -- enough to build and test. Happy to answer any questions!
