We have looked at the fundamentals of astronomy. Let us understand how timekeeping is related to the astronomical cycles or patterns. For that, we will first need to answer the question,”What is the basis of the day, month and year, which we refer to for every human activity anywhere in the world?” The day, month and year in timekeeping is synchronized with the cycles of celestial objects in the sky.

Indian timekeeping is based on distant celestial bodies and is inseparable from astronomy. The positions of these celestial bodies, as observed from the earth, follow periodic patterns. Patterns means mathematics. So timekeeping is essentially astronomical mathematics, where the exact positions and trajectories of celestial bodies are mathematically calculated and used to reckon time on earth.
