There was a time when time itself was undefined...no one knew the difference between a minute, an hour, or a day. Then people began making tools to measure time using the sun, the moon, and water. Using this knowledge they began to build clocks and from that created calendars made up of months and years.

Explains the concept of time, looks at how time is measured in months, and discusses some of the events and seasonal changes that occur in each month of the year.
