Python Datetime

← Previous Next →

Python has a built-in module called datetime to work with dates and times.

To use it, you must import the module:

import datetime

🔹 Get Current Date and Time

import datetime
now = datetime.datetime.now()
print(now)

🔹 Get Only Date or Time

today = datetime.date.today()
print(today)

current_time = datetime.datetime.now().time()
print(current_time)

🔹 Create a Custom Date

d = datetime.datetime(2023, 5, 17)
print(d)

🔹 Get Year, Month, Day

now = datetime.datetime.now()
print(now.year)
print(now.month)
print(now.day)

🔹 Format Date Output

now = datetime.datetime.now()
print(now.strftime("%Y-%m-%d"))  # 2025-06-21
print(now.strftime("%A"))        # Friday
print(now.strftime("%I:%M %p"))  # 05:30 PM

Common format codes:

Code Meaning
%Y Year
%m Month (01–12)
%d Day
%H Hour (00–23)
%I Hour (01–12)
%M Minute
%p AM or PM
%A Weekday name

🔹 Timedelta (Add or Subtract Time)

from datetime import timedelta, datetime

today = datetime.now()
future = today + timedelta(days=10)
past = today - timedelta(days=5)
print(future)
print(past)

🔹 ISO Format

print(datetime.now().isoformat())

🧪 Try It Yourself

  • Get today’s date

  • Format it into DD-MM-YYYY

  • Add 7 days to current date

  • Extract time only from current timestamp
