This “Date and Time” exercise aims to help Python developers learn and practice frequently occurring DateTime-related problems. Here, I am providing 10 date and time coding problems to solve to help you brush up your coding skills.

This Python DateTime exercise contains 10 coding questions, each with a provided solution. This coding exercise will help you to 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
• Date and time 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.

print(datetime_object)Code language: Python (python)

Exercise 3: Subtract a Week From a Given Date

Write a code to subtract a week (7 days) from a given date.

Refer: TimeDelta in Python

Given:

given_date = datetime(2020, 2, 25)Code language: Python (python)

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)Code language: Python (python)

Exercise 4: Format DateTime

Write a code to print date in the following format.

Day_name  Day_number  Month_name  Year

Refer: Python DateTime Format Using Strftime()

Given:

given_date = datetime(2020, 2, 25)Code language: Python (python)

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'))Code language: Python (python)

Exercise 5: Find Day of Week

Write a code to find the day of the week of a given date.

Given:

given_date = datetime(2020, 7, 26)Code language: Python (python)

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'))Code language: Python (python)

import calendar
from datetime import datetime

given_date = datetime(2020, 7, 26)
weekday = calendar.day_name[given_date.weekday()]
print(weekday)Code language: Python (python)

Exercise 6: Add Week to Given Date

Write a code to 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)Code language: Python (python)

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)Code language: Python (python)

Exercise 7: Print Current Time in Milliseconds

import time

milliseconds = int(round(time.time() * 1000))
print(milliseconds)Code language: Python (python)

Exercise 8: Convert Datetime into String

Write a code to convert a given datetime object into a string.

Given:

given_date = datetime(2020, 2, 25)Code language: Python (python)

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)Code language: Python (python)

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

Given:

# 2020-02-25
given_date = datetime(2020, 2, 25).date()Code language: Python (python)

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)Code language: Python (python)

Exercise 10: Calculate Days Between Two Dates

Write a code to calculate the days between two dates.

Refer: Python Difference Between Two Dates in Days.

Given:

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

# 2020-09-17
date_2 = datetime(2020, 9, 17)Code language: Python (python)

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")
