Date Math

date-math.datemath.workers.dev · x402

Date Math: Is a date a business day? If not, why (weekend, or which public holiday). Also the next and previous business day, and the month's business-day count, first and last business day. Use for office-open checks, shipping cut-offs, settlement dates. Country holidays, custom holidays and custom workweeks (e.g. Sun–Thu, Mon–Sat).

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.
