Frequently Asked Questions
How do I calculate the time difference between 9:45 PM and 2:30 AM?
When calculating time differences that span midnight, select "Span multiple days" in our Time Difference Calculator. Enter 21:45 as the start time (9:45 PM in 24-hour format) and 02:30 as the end time, check the "Span multiple days" option, and click calculate. The result will show 4 hours and 45 minutes.
Can I calculate decimals in time conversions?
Yes, our Time Conversion feature supports decimal values. For example, if you want to convert 1.5 hours to minutes, simply enter 1.5 in the value field, select "hours" as the source unit and "minutes" as the target unit. The calculator will show the result as a decimal (90 minutes in this example).
How do I calculate time for billing purposes?
For billing calculations, use the Time Difference Calculator to find the exact duration worked. You can then use the Time Conversion feature to convert the hours and minutes to decimal hours if needed (e.g., converting 7 hours and 15 minutes to 7.25 hours). Many billing systems require decimal hour format for accurate invoicing.
Does the calculator account for daylight saving time changes?
This basic Time Calculator does not automatically account for daylight saving time changes. It performs direct calculations based on the hours and minutes you input. For calculations that span daylight saving time changes, you may need to manually adjust the times or use a specialized calendar-based calculator.
