Mixing units is the fastest way to get a believable-but-wrong working days calculator uk answer. Double-check whether each field expects a percent as 7.5 versus 0.075, whether money is monthly or annual, and whether distances or weights use the same system throughout (Start date (YYYY-MM-DD), End date (YYYY-MM-DD), Bank holidays to subtract).
