Python Date and Time Exercise with Solutions

This Date and Time exercise aims to help Python developers to learn and practice DateTime-related frequently occurring problems. Here I am providing 10 date and time programs to help you in brushing up your coding skills. All questions are tested on Python 3. Knowledge of Date and time manipulation is necessary if you want to be a good Python developer.

This Python DateTime exercise include the following: –

• It contains 10 questions and solutions provided for each question.
• This coding exercise is nothing but Python Date and time assignments to solve, where you can solve and practice different dates and time programs and challenges.

It covers questions on the following topics:

• Working with dates and times in Python
• Functions available in the Python datetime module
• Convert and manipulate date and time in a specific format
• Dates and times arithmetic

When you complete each question, you get more familiar with the DateTime operations. Let us know if you have any alternative solutions. It will help other developers.

Use Online Code Editor to solve exercise questions.

Exercise 1: Print current date and time in Python

See: Get Current Date and Time in Python

import datetime

# Print date and time
print(datetime.datetime.now())

# only time
print(datetime.datetime.now().time())

from time import gmtime, strftime

print(strftime("%Y-%m-%d %H:%M:%S", gmtime()))

Exercise 2: Convert string into a datetime object

For example, You received the following date in string format. Please convert it into Python’s DateTime object.

Refer: Python String to DateTime

Given:

date_string = "Feb 25 2020 4:20PM"

Expected output:

2020-02-25 16:20:00

from datetime import datetime

date_string = "Feb 25 2020  4:20PM"
datetime_object = datetime.strptime(date_string, '%b %d %Y %I:%M%p')
print(datetime_object)

Exercise 3: Subtract a week (7 days)  from a given date in Python

Refer: TimeDelta in Python

Given:

given_date = datetime(2020, 2, 25)

Expected output:

2020-02-18

from datetime import datetime, timedelta

given_date = datetime(2020, 2, 25)
print("Given date")
print(given_date)

days_to_subtract = 7
res_date = given_date - timedelta(days=days_to_subtract)
print("New Date")
print(res_date)

Exercise 4: Print a date in a the following format

Day_name  Day_number  Month_name  Year

Refer: Python DateTime Format Using Strftime()

Given:

given_date = datetime(2020, 2, 25)

Expected output:

Tuesday 25 February 2020

Refer Date format codes for help

from datetime import datetime

given_date = datetime(2020, 2, 25)
print("Given date is")
print(given_date.strftime('%A %d %B %Y'))

Exercise 5: Find the day of the week of a given date

Given:

given_date = datetime(2020, 7, 26)

Expected output:

Sunday

from datetime import datetime

given_date = datetime(2020, 7, 26)

# to get weekday as integer
print(given_date.today().weekday())

# To get the english name of the weekday
print(given_date.strftime('%A'))

import calendar
from datetime import datetime

given_date = datetime(2020, 7, 26)
weekday = calendar.day_name[given_date.weekday()]
print(weekday)

Exercise 6: Add a week (7 days) and 12 hours to a given date

Given:

# 2020-03-22 10:00:00
given_date = datetime(2020, 3, 22, 10, 0, 0)

Expected output:

2020-03-29 22:00:00

from datetime import datetime, timedelta

given_date = datetime(2020, 3, 22, 10, 00, 00)
print("Given date")
print(given_date)

days_to_add = 7
res_date = given_date + timedelta(days=days_to_add, hours=12)
print("New Date")
print(res_date)

Exercise 7: Print current time in milliseconds

import time

milliseconds = int(round(time.time() * 1000))
print(milliseconds)

Exercise 8: Convert the following datetime into a string

Given:

given_date = datetime(2020, 2, 25)

Expected output:

"2020-02-25 00:00:00"

from datetime import datetime

given_date = datetime(2020, 2, 25)
string_date = given_date.strftime("%Y-%m-%d %H:%M:%S")
print(string_date)

Exercise 9: Calculate the date 4 months from the current date

Given:

# 2020-02-25
given_date = datetime(2020, 2, 25).date()

Expected output:

2020-06-25

from datetime import datetime

from dateutil.relativedelta import relativedelta

# 2020-02-25
given_date = datetime(2020, 2, 25).date()

months_to_add = 4
new_date = given_date + relativedelta(months=+ months_to_add)
print(new_date)

Exercise 10: Calculate number of days between two given dates

Given:

# 2020-02-25
date_1 = datetime(2020, 2, 25)

# 2020-09-17
date_2 = datetime(2020, 9, 17)

Expected output:

205 days

from datetime import datetime

# 2020-02-25
date_1 = datetime(2020, 2, 25).date()
# 2020-09-17
date_2 = datetime(2020, 9, 17).date()

delta = None
if date_1 > date_2:
    print("date_1 is greater")
    delta = date_1 - date_2
else:
    print("date_2 is greater")
    delta = date_2 - date_1
print("Difference is", delta.days, "days")
