This behavior is present both before and after #19608/#19540.

per = pd.Period('0001-01-01', freq='B')
>>> per + 1
Period('0001-01-02', 'B')
>>> per - 1
Period('0001-01-05', 'B')
>>> per - 4
Period('0001-01-02', 'B')
>>> per - 5
Period('0000-12-25', 'B')

Making a PR for this now, parking a related issue that is going in an xfail for the time being:

per = Period('0001-01-01', freq='B')
>>> per.to_timestamp()
Timestamp('1754-08-30 22:43:41.128654848')
