Python’s built-in datetime module allows you to work with dates, times, and timedeltas easily.

To use it:

import datetime

1. Get Current Date and Time

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

Output:

2025-06-16 06:30:12.123456
Explanation:
datetime.now() returns the current local date and time with microseconds.

2. Get Only Date or Time

import datetime
today = datetime.date.today()
print("Date:", today)
now = datetime.datetime.now()
print("Time:", now.time())

Output:

Date: 2025-06-16
Time: 06:30:12.123456

Explanation:

• date.today() returns the current date.
• now.time() extracts only the time from a datetime object.

3. Create a Custom Date or Time

import datetime
birthday = datetime.date(1990, 5, 10)
print(birthday)

Output:

1990-05-10

Explanation:
Creates a date object with year, month, day.

4. Get Day, Month, Year, Weekday

import datetime
d = datetime.date(2025, 6, 16)
print("Day:", d.day)
print("Month:", d.month)
print("Year:", d.year)
print("Weekday:", d.weekday())  # Monday = 0

Output:

Day: 16
Month: 6
Year: 2025
Weekday: 0

5. Format Dates with strftime()

import datetime
now = datetime.datetime.now()
print(now.strftime("%d/%m/%Y"))
print(now.strftime("%A, %B %d, %Y"))

Output :

16/06/2025
Monday, June 16, 2025

Explanation:

• %d = day, %m = month, %Y = year
• %A = weekday name, %B = month name

6. Parse Strings into Dates with strptime()

import datetime
date_str = "21-06-2025"
date_obj = datetime.datetime.strptime(date_str, "%d-%m-%Y")
print(date_obj)

Output:

2025-06-21 00:00:00

Explanation:
Converts a date string into a datetime object.

7. Timedelta: Date Arithmetic

import datetime
today = datetime.date.today()
tomorrow = today + datetime.timedelta(days=1)
print("Tomorrow:", tomorrow)
past = today - datetime.timedelta(days=7)
print("7 days ago:", past)

Output:

Tomorrow: 2025-06-17
7 days ago: 2025-06-09

Explanation:
timedelta represents a time difference. You can add or subtract days, hours, etc.

8. Get UTC Time

import datetime
utc_now = datetime.datetime.utcnow()
print(utc_now)

Output:

2025-06-16 01:00:12.345678

Explanation:
Returns the current UTC date and time.

9. Pause Execution with time.sleep()

import time
print("Wait 3 seconds...")
time.sleep(3)
print("Done!")

Output:

Wait 3 seconds...
Done!

Explanation:
time.sleep(seconds) pauses the program for the given number of seconds.
