Weeks divide cleanly into days — seven each, no exceptions — making them the most reliable intermediate unit for spans too long for daily counting but shorter than months. Pregnancy tracking, training plans and lease terms lean on weekly precision for exactly this reason.
Converting weeks into months introduces fuzziness because months average about 4.345 weeks, not four. The calculator shows approximate month equivalents so rough planning stays honest about its own rounding.
