1. find the nearest EP that precedes the observation time in the nautical calendar

2. EP is shown in even-numbered hours, so if you want EP at any given time, you can find the correction value from the P.P. table in the right column, because unlike solar time, there is a large amount of variation.

3. The hour angle can be easily obtained by adding the observation time (U.T.C.) to the EP obtained in step 2.

4. Since the time angle obtained is in hours, if you wish to obtain it in angles, simply multiply it by 15. 
 
5. In the case of Declination, find the closest Declination before the observation time.
In the case of solar declination, find the P.P. value of declination from the P.P. value in the right column. At this time, if the Declination value is larger, add it.

How to calculate the Planet's midday time.(Venus)

Find the midday time of January 1, 165°E 10:00:00 U.T.C.

1. subtraction is made from 24:00, since it is not always near 12:00, as is the case with the sun.

2. since the observation time is 10:00 U.T.C., find the 10:00 EP from the Nautical Almanac

3. this gives us L.M.T. If we want to find G.M.T., we can add or subtract L.T. L.T. is also the longitude time, which is a number obtained by dividing the longitude by 15. It is also calculated by East longitude - and West longitude +.

4. On the column of each planet, you can also obtain the approximate midday time of the day. (L.M.T.)
