Why does Jeddah need its own calendar?
A hot coastal climate combines two challenges that rarely meet in other cities: dust blowing in from the land and humidity rolling in from the sea. On heavy dust days a fine layer settles on glass and AC units, and on humid days that layer turns sticky and becomes marks that a dry cloth will not lift.
That is why organised households prefer a calendar that adapts to the season: a fixed routine for daily hygiene, then seasonal jobs added when needed instead of waiting for a problem to show.
