Examples

>>> ts = pd.Timestamp(2022, 12, 1)
>>> ts + pd.offsets.YearBegin()
Timestamp('2023-01-01 00:00:00')

>>> ts = pd.Timestamp(2023, 1, 1)
>>> ts + pd.offsets.YearBegin()
Timestamp('2024-01-01 00:00:00')

If you want to get the start of the current year:

>>> ts = pd.Timestamp(2023, 1, 1)
>>> pd.offsets.YearBegin().rollback(ts)
Timestamp('2023-01-01 00:00:00')
