From the French demeurer — to linger. For centuries of maritime trade, a charterer got an agreed number of “lay days” to load or unload a ship; hold the vessel longer and you owed the owner demurrage — a charge for every day of delay. Admiralty courts have enforced it for hundreds of years: delay has a price, counted daily, owed without argument. Azimuth Demurrage applies the same ancient rule to claim money: the carrier’s own estimate starts the statutory clock, and every day they hold your payment past the deadline accrues interest at the state’s legislated rate. Ships pay for the days they hold the cargo. So do carriers.
Computed by the backend on every hourly pass: earliest carrier estimate starts the statutory window, payments net against the carrier’s own number, and the meter runs on what’s left. This is the same data that prints in the daily digest.
