Sources and limits
Final annual editions 1404 and 1405 supply all 730 paired dates. Earlier and later years are outside this edition.
The separate 1405 holiday list supplies 26 published holiday dates. Holiday labels are not supplied for 1404; an empty label does not declare a working day.
This is a fixed published edition. Later official changes and moon-sighting announcements are not inferred. Weekly rest days are not automatically added.
The centre’s general leap-year reference disagrees with its final annual calendars for some years; this tool uses the final annual calendars and does not extrapolate an arithmetic leap cycle.
The official page for 1406 stated that preparation was in progress when reviewed. No 1406 dates are synthesized.
