Python - Retrieving parts of a datetime object using strftime()

We can use built-in strftime() function to get the required part of a given date.
Samples below.

Year

Year can be fetched as full year or just the last 2 digits.

from datetime import datetime
dt = datetime(2022, 1, 1, 14, 00, 00)
print("Full Year: " + datetime.strftime(dt, '%Y'))
print("2 digit Year: " + datetime.strftime(dt, '%y'))

Output: Full Year: 2022 2 digit Year: 22

Month

Month can be displayed as a number (01 - 12) or full name or abbreviated name.

from datetime import datetime
dt = datetime(2022, 1, 1, 14, 00, 00)
print("Month as number: " + datetime.strftime(dt, '%m'))
print("Month (abbr.): " + datetime.strftime(dt, '%b'))
print("Month name: " + datetime.strftime(dt, '%B'))

Output: Month as number: 01 Month (abbr.): Jan Month name: January

Days

Day number of the year (000 - 366), day number of the month (00 - 31) or day number of the week (0 - 6. Sunday is 0).

from datetime import datetime
dt = datetime(2022, 5, 20, 14, 00, 00)
print("Day of year: " + datetime.strftime(dt, '%j'))
print("Day of month: " + datetime.strftime(dt, '%d'))
print("Day of week: " + datetime.strftime(dt, '%w'))

Output: Day of year: 140 Day of month: 20 Day of week: 5

Weekday

Weekday abbreviated or weekday full.

from datetime import datetime
dt = datetime(2022, 5, 20, 14, 00, 00)
print("Weekday (abbr.): " + datetime.strftime(dt, '%a'))
print("Weekday full: " + datetime.strftime(dt, '%A'))

Output: Weekday (abbr.): Fri Weekday full: Friday

Week number

Week number of the year with Sunday or Monday as the first day of the week (00 - 53).

from datetime import datetime
dt = datetime(2022, 5, 22, 14, 00, 00)
print("Week number (Sunday as first day): " + datetime.strftime(dt, '%U'))
print("Week number (Monday as first day): " + datetime.strftime(dt, '%W'))

Output: Week number (Sunday as first day): 21 Week number (Sunday as first day): 20

Time

Hours (12 or 24 hour format), minutes, seconds, microseconds and AM or PM.

from datetime import datetime
dt = datetime(2022, 5, 22, 14, 20, 30, 234567)
print("Hours (12 hour format): " + datetime.strftime(dt, '%I'))
print("Hours (24 hour format): " + datetime.strftime(dt, '%H'))
print("Minutes: " + datetime.strftime(dt, '%M'))
print("Seconds: " + datetime.strftime(dt, '%S'))
print("Microseconds: " + datetime.strftime(dt, '%f'))
print("AM or PM: " + datetime.strftime(dt, '%p'))

Output: Hours (12 hour format): 14 Hours (24 hour format): 02 Minutes: 20 Seconds: 30 Microseconds: 234567 AM or PM: PM

Time zone

Time zone and UTC offset as +-HHMM[SS[.ffffff]]

import datetime
dt = datetime.datetime.now(datetime.timezone.utc)
print("UTC offset: " + datetime.datetime.strftime(dt, '%z'))
print("Time zone: " + datetime.datetime.strftime(dt, '%Z'))

Output: UTC offset: +0000 Time zone: UTC
