Question

Name any two periodic events used in ancient time to count intervals of time?

Answer 1

In ancient time, many events occurring in nature were used to count intervals of time as these events repeat after a particular interval of time. Everyday, sun rises in the morning. Hence, the time interval between 2 sunrise was called as day. Similarly, every month, full moon is observed. Hence, the time interval between 2 full moon was considered as a month.
