Frequently asked questions
How many work hours are in a year?
A standard full-time year is 40 hours × 52 weeks = 2,080 hours. The salary to hourly calculator lets you change hours per week and weeks per year.
Does the date calculator count both the start and end date?
You can choose. By default the start date is not counted and the end date is; switching to inclusive adds one day so both dates count.
Can I calculate timesheet hours with unpaid breaks?
Yes. The hours calculator subtracts break time for each day and totals the week in hours and minutes and in decimal hours.
