Productivity calculators

Plan meetings, count business days, and map work hours across time zones.

These tools handle recurring scheduling and time calculations that are straightforward in concept but tedious to do by hand. The time zone meeting planner overlays up to eight locations on a UTC grid, marks DST transitions, and highlights overlapping business hours — useful for distributed teams scheduling recurring calls across multiple continents. The US and UK working days calculators count business days between two dates using verified public holiday data through 2030, including regional bank holiday variations for England, Scotland, Wales, and Northern Ireland.

The date difference calculator breaks down intervals in calendar days, working days, weeks, months, and years simultaneously, and the Eisenhower Matrix tool helps prioritize tasks across the urgent/important quadrant grid. All calculators run client-side with no sign-in, making them safe to use for internal scheduling without exposing team data.
