What role does astronomy play in real life? Please give an example.

Do you know why there are 60 seconds in a minute? Determine by observing the stars. Do you know how humans define the length of 1 second? Determine by studying astronomy. Do you know why there are 365 days in a year and why there are leap years? Do you know why there are 24 solar terms? This is all deduced by the ancients through repeated observation and mathematical calculation of the laws of star motion. Do you know why humans can grow food? Because human beings discovered the existence of time by observing astronomy, they divided time into spring, summer, autumn and winter. . If you don't want to live a life without the concept of time, if you don't want to live a life without food. Then you should know that astronomy is meaningful.
