How this service works
Adds N French business days to a date (?start=2026-07-13&add=30) or counts them over a range (?from=2026-07-01&to=2026-09-30). Skips weekends and the 11 French legal public holidays (movable feasts computed via Butcher-Meeus). mode=ouvres (Mon-Fri, default) or ouvrables (Mon-Sat). Deterministic local computation, JSON.
Output
A JSON object containing the computed result — either a destination date after adding N business days (mode: add) or a count of business days within a date range (mode: count). Includes details on skipped weekends and French public holidays computed via the Butcher-Meeus algorithm for movable feasts. Works in both jours ouvrés (Mon–Fri) and jours ouvrables (Mon–Sat) modes.
Example use cases
Example prompt
