Business Days Calculator
Intelligently calculates the net number of workdays between two dates, automatically excluding weekends and statutory holidays of various countries. Supports holiday settings for multiple regions and provides detailed date analysis reports, making it an ideal tool for project management, payroll, and leave tracking.
Each result states its calendar source and coverage. Verified annual arrangements are used when available; otherwise dates follow calendar rules. Strict queries reject incomplete coverage.
Inputs are converted to dates in the selected time zones before counting. Reversed dates and their inclusion settings are swapped together.
Manual adjustments override the weekly schedule, holidays and date-type filter. Enter local or employer arrangements yourself; annual make-up workdays are not supplied automatically.
