How it works
Use date difference mode to find the gap in days and business days between two dates. Use worked time mode to enter a shift with an optional break and get total hours and an estimated pay amount.
Business days: count weekdays between start and end dates, inclusive. Pay: (end time − start time − break) in hours × hourly rate.
1 Jan to 31 Mar = 65 business days. 09:00–17:30 with a 30-minute break at 250 kr/h = 8 hours = 2,000 kr.
Calculating notice periods, invoicing work hours, estimating project timelines, or checking overtime pay.
What do you want to do next?
Use the result with percentages or savings goals to see what extra hours actually do over time.
