Questions
How do I add hours and minutes?
Add the minutes together, add the hours together, then turn every 60 minutes into 1 hour. The calculator does this for each row you fill in.
Can I subtract time too?
Yes. Set a row to Subtract and its hours and minutes come off the total. If more is subtracted than added, the answer shows a minus sign.
What if I type more than 59 minutes?
That works. 90 minutes in a row counts as 1 hour 30 minutes.
Why is there a decimal answer?
Some time sheets and payroll forms use decimal hours, where 7 hours 45 minutes is written 7.75. The decimal line shows that form, rounded to two places.
