  dt: Union[None, LocalDate, str, datetime.date, datetime.time, datetime.datetime, numpy.datetime64, pandas.Timestamp]
  ) -> LocalDate

Parameters

Parameter	Type	Description
dt	Union[None, LocalDate, str, datetime.date, datetime.time, datetime.datetime, numpy.datetime64, pandas.Timestamp]	The date-time value to convert to a Java LocalDate. A string in the form of [-]PTnHnMnS, with n being numeric values; e.g., PT1H for one hour, PT1M for one minute, or -PT1M5.5S for negative one minute and 5.5 seconds.

Returns

Returns a LocalDate.

Examples

from deephaven.time import to_j_local_date, dh_today

ld = to_j_local_date(dh_today())
print(ld)

Log

from deephaven.time import to_j_local_date
import numpy as np
import pandas as pd
import datetime

dt_date = datetime.date(2024, 9, 2)
dt_dt = datetime.datetime(2024, 9, 2)
np_dt64 = np.datetime64(12, "h")
pd_dt = pd.Timestamp("2024-11-11")

dt_date_ld = to_j_local_date(dt_date)
dt_dt_ld = to_j_local_date(dt_dt)
np_dt64_ld = to_j_local_date(np_dt64)
pd_dt_ld = to_j_local_date(pd_dt)
date_str_ld = to_j_local_date("2024-10-12")

print(dt_date_ld)
print(dt_dt_ld)
print(np_dt64_ld)
print(pd_dt_ld)
print(date_str_ld)
