Add Date Attributes (Crime Analysis and Safety)

Summary

Adds fields containing date or time properties from an input date field, for example, day full name, day of the month, month, and year.

Usage

• Existing fields will be overwritten in the Input Table value when an existing field name is the same as the defined Output Field Name value.

• The values of the new fields will not update automatically if the values of the Date Field parameter are updated. Run this tool when the Date Field parameter is updated.

Code sample

AddDateAttributes example 1 (Python window)

The following Python window script demonstrates how to use the AddDateAttributes function in immediate mode.

import arcpy
arcpy.env.workspace = r"C:\data\city_pd.gdb"
arcpy.ca.AddDateAttributes("CallsForService", "CALLDATE")

AddDateAttributes example 2 (stand-alone script)

The following Python script demonstrates how to use the AddDateAttributes function in a stand-alone script.

# Name: AddDateAttributes.py
# Description: Add fields for hour, day full name, month, day of the month, 
#              and year to the calls for service data based on the call date 
#              field.

# Import system modules
import arcpy

# Set environment settings
arcpy.env.workspace = r"C:/data/city_pd.gdb"

# Set local variables
in_features = "CallsForService"
date_field = "CALLDATE"

# Customize the name of output date attribute fields
# ["Output Time Format", "Output Field Name"]
day_name_field = ["DAY_FULL_NAME", "CALL_DAYOFWEEK"]
day_week_field = ["DAY_OF_WEEK", "CALL_DAYNUM"]
hour_field = ["HOUR", "CALL_HOUR"]
month_field = ["MONTH", "CALL_MONTH"]
day_num_field = ["DAY_OF_MONTH", "CALL_DAY"]
year_field = ["YEAR", "CALL_YEAR"]

date_attributes = [day_name_field, day_week_field, hour_field, month_field, day_num_field, 
                   year_field]

# Execute AddDateAttributes
arcpy.ca.AddDateAttributes(in_features, date_field, date_attributes)
