SLA / Business-Hours Deadline Calculator
Add business hours or business days to a start time, skipping weekends, holidays and non-working hours.
Overview
A support-desk SLA and business-hours deadline calculator. Give it a start time and a number of business hours or business days to add, plus your working window, workdays and holidays, and it returns the exact deadline (date, time and day of week), the business hours consumed, and the real calendar time elapsed. Ideal for ticketing systems, response-time commitments and project due-date planning. Dates are parsed with invariant culture (yyyy-MM-dd HH:mm).
