calendar_weekday
shallowdev.almanack/almanack · Verify this server
Which weekday a date falls on, as a 0-based index into the calendar's own week plus its name. Exact; never estimates. Returns weekday null when the date is an intercalary day the week does not count: those days sit outside the cycle and the week resumes after them exactly where it left off. Fails if the calendar defines no week rather than inventing a seven-day one.
