6 Timestamp limitations
Since pandas represents timestamps in nanosecond resolution, the timespan that can be represented using a 64-bit integer is limited to approximately 584 years:
In [1]: pd.Timestamp.min
Out[1]: Timestamp('1677-09-22 00:12:43.145225')
In [2]: pd.Timestamp.max
Out[2]: Timestamp('2262-04-11 23:47:16.854775807')
See here for ways to represent data outside these bound.
