Working in Productivity
Not every tool needs to be complex to be valuable. ASG Tools' productivity category houses the small, sharp instruments: a business-days counter that answers 'how many working days between these dates — excluding weekends and these four holidays?' in one glance, and the sibling date and count utilities that ship in later batches. These are the questions you currently answer by counting on your fingers, opening a spreadsheet, or guessing — and guessing is how project timelines quietly slip.
The business-days counter is exact: it walks the calendar, skips Saturdays and Sundays, subtracts the holidays you list (with a one-click US federal holiday preset), and shows its work — total days, weekend days, holiday exclusions and the final count. Project managers use it for contract deadlines; HR teams for notice periods; freelancers for payment terms like net-30 business days.
Everything computes locally in your browser. There is no reason a date calculation needs a server, and now it does not have one. More productivity micro tools — timers, countdowns, unit converters — arrive in upcoming batches.
