Tool updates
A record of changes to tool behavior and explanations.
- Calculator results are cleared after relevant inputs change, so an earlier answer is not mistaken for the current calculation.
- Number fields reject ambiguous comma formatting and show the supported decimal and thousands formats.
- Discount Calculator now applies stacked discounts and compares them with a competing single discount.
- Days Between Dates now calculates business days after excluding supplied holiday dates.
- Sentence estimates protect common titles such as Dr. and Ms., and initials. Remaining ambiguity is explained on the Word Counter page.
- Calendar validation correctly handles leap years in the years 1–99.
- The homepage introduces the tools in less space, and guides include additional offer-comparison and date-counting examples.
