Dates
Use Python’s datetime and zoneinfo modules to create, format, parse, and manipulate dates and times efficiently.
Working with Dates and Times
Using the datetime Module
Python’s datetime module provides classes to handle dates and times.
pythonCopyEditfrom datetime import datetime, date, time # Current date and time now = datetime.now() print(now) # Creating specific dates and times birthday = date(1990, 5, 17) meeting_time = time(14, 30) print(birthday, meeting_time)
Formatting Dates and Times
Format date/time as strings using strftime:
pythonCopyEditnow = datetime.now() formatted = now.strftime("%Y-%m-%d %H:%M:%S") print(formatted) # Example: 2025-07-07 12:30:45
Parsing Strings to Dates
Convert strings to datetime objects with strptime:
pythonCopyEditdate_str = "2025-07-07 12:30:45" dt = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S") print(dt)
Handling Timezones
Use the zoneinfo module (Python 3.9+):
pythonCopyEditfrom datetime import datetime from zoneinfo import ZoneInfo now_utc = datetime.now(tz=ZoneInfo("UTC")) now_ny = now_utc.astimezone(ZoneInfo("America/New_York")) print(now_utc) print(now_ny)
