Sun and Moon movement over Kathmandu sky: Astronomical reading

Solar NOON and Sun and Moon movement

It is not necessary that solar noon coincides with civil (or local) noon (12:00PM on your clock) all the time. Infact, in Kathmandu, solar noon occurs at exact 12:00PM for about 20 to 30 days in a years, for rest of the year it sways around as much 15 to 20 minutes ahead or after the civil noon.

Graph below represents the solar noon fluctuation pattern in Kathmandu for year 2011.
