Each tool performs real calendar arithmetic for its specific question. Results are rendered on the server for crawlability, then recalculated in the browser so the visible date and time match the visitor's device timezone.
Days, weeks, and date-difference tools include every calendar day. Saturdays, Sundays, month lengths, and leap years remain part of the calculation.
Business-day tools count Monday through Friday and skip weekends. Public holidays are not removed because holiday schedules differ by country and organization.
Month calculations move by real calendar months. When a target month is shorter, the result uses the final valid day instead of assuming every month contains 30 days.
Live countdowns and clock tools use the timezone reported by the visitor's browser. This prevents one fixed server timezone from producing the same clock answer for every country.
