add the degrees of two places you want to find. Then multiply the answer with 4.Then divide it with 60.The answer you get is the time difference between two places
You can calculate the longitude of a place when time is given using the Greenwich solar time.
24
We use longitude and latitude when looking at a map to calculate time.
As all the lines of longitude meet there, it is impossible to calculate time there.
30degrees
To calculate standard time, subtract the equation of time from the sundial time, then subtract the longitude from the answer you get.
360° ÷ 24 hr = 15°/hr
You can calculate the time difference between two locations by dividing the difference in longitude by 15 degrees, as each 15-degree interval represents a one-hour time difference. East is positive and west is negative when determining the direction of the time change.
Take for example: 75°57′8″W, a line of longitude. We all know that lines of longitude measure the time zones. There are 360 degrees of longitude, and there are 24 hours in a day. Therefore, an hour would be 15 degrees longitude (360/24). 75° would be the number of degrees of longitude. If we take 75 and divide it by 15, we get the number of hours that we want, in this case, 5 hours. 57′ would be the number of minutes. 8″ would be the number of seconds. Sometimes, there are even milliseconds. They are the decimals after the number of
You cannot since most shapes do not have a longitude.
You cannot reliably determine a place's time zone by its longitude. The best you can do is to calculate the local mean time for the longitude. That is because every country is free to choose whatever time zone(s) it wants, and therefore there are many places where the time zone is not the local mean time rounded to the nearest hour.To calculate the local mean time at a certain longitude when it's noon UTC, using x° for x° east and -x° for x° west, add 180° to the longitude, multiply by 4 minutes per degree, and divide by 60 minutes per hour.
Every latitude extends all the way around the Earth, and is unrelated to the time at any place.If you were to consider longitude instead, the difference in solar time between two longitudes is(longitude #1)degrees minus (longitude #2)degrees/15 hours.
