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

2. EP is shown in even 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 to the time of observation.
In the case of solar declination, find the P.P. value of the declination from the P.P. value in the right column. If the Declination value is larger at this time, 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. subtract from 24:00, since it is not always close to 12:00 like the sun.

2. since the observation time is 10:00 U.T.C., we 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 get the approximate midday time of the day. (L.M.T.)
