how to calculate time difference using latitude and longitude?

Because one day is 24 hours long one can easily use time to calculate longitude. One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour). Suppose an observer sets his accurate watch to 12:00 at noon in Greenwich, England and then travels a great distance.

The line of longitude is read as 2 degrees (2°), 10 minutes (10′), 26.5 seconds (12.2”) east. The line of latitude is read as 41 degrees (41), 24.2028 minutes (24.2028) north. The coordinate for the line of latitude represents north of the Equator because it is positive.

Finding the number of hours or the time between two times / dates is simple, just subtract the start date/time from the end date/time and multiply the result by 24 hours.

To subtract time, type in =B2-B1, and it'll return the elapsed time. The answer is displayed as an AM time, so to change that, right click and select Format Cells and change it to h:mm. It'll return the answer in time format (7:35, or 7 hours and 35 minutes).

Total minutes between two times: To calculate the minutes between two times, multiply the time difference by 1440, which is the number of minutes in one day (24 hours * 60 minutes = 1440).

Degrees, Minutes, Seconds The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S). Each degree can be broken into 60 minutes ('). Each minute can be divided into 60 seconds (”).

If longitude is known, the time of astronomical noon can be calculated. For example, Lincoln, NE, is at longitude 96.7° W. 96.7°/(15°/hour)=6.4467 hours. Being Central Time, Lincoln is 6 hours away from Greenwich Mean Time, so astronomical noon is (6.4467 - 6) hours = 0.4467 hours = 26.8 minutes from 12:00.
