Before we get to pandas, it can help to be aware of and understand core Python's date and time functionality. The datetime module provides three distinct data types, date, time, and datetime. Formally, a date is a moment in time consisting of just the year, month, and day. For instance, June 7, 2013 would be a date.

A datetime consists of both the elements of a date and time together.
On the other hand, pandas has a single object to encapsulate date and time called a Timestamp. It has nanosecond (one-billionth of a second) precision and is derived from NumPy's datetime64 data type. Both Python and pandas each have a timedelta object...
