Enter data manually
Manual mode is needed if you want to use the data of another astronomical source. The most accurate option is to indicate a true sunny noon. If it is not known, it can be roughly defined as the middle between the sunrise and sunset.
At 12:00 solar time, the true sunny noon is taken for specific coordinates and dates. Then, to the local noon time, the difference between the required solar time and 12:00 is applied.
Local time = Sunny Noon + (Solar Time 12:00)
