## Frequently Asked Questions

How long is an hour on a time card?

For a full time card, please use the Time Card Calculator. An hour is most commonly defined as a period of time equal to 60 minutes, where a minute is equal to 60 seconds, and a second has a rigorous scientific definition. There are also 24 hours in a day. Most people read time using either a 12-hour clock or a 24-hour clock.

What are the numbers on a 24 hour clock?

A 24-hour clock typically uses the numbers 0-23, where 00:00 indicates midnight, and a day runs from midnight to midnight over the course of 24 hours. This time format is an international standard, and is often used to avoid the ambiguity resulting from the use of a 12-hour clock.

How do you read time using a 12-hour clock?

Most people read time using either a 12-hour clock or a 24-hour clock. A 12-hour clock uses the numbers 1-12. Depending on the clock being used, most analog clocks or watches may not include an indication of whether the time is in the morning or evening.

What is the correct way to enter hours and minutes?

You can use a period. instead of a colon : to delimit the hour and minute segments. For example, entering 7.15 is the same as entering 7:15, 5.30 = 5:30 and 12.8 = 12:08. Use military time when spanning large time blocks. E.g., instead of 6 (am) to 6 (pm), enter 6 and 18.
