Python | Find yesterday today and tomorrow date

python | find yesterday today and tomorrow date: We can handle Data objects by importing the module datetime and timedelta to work with dates. datetime module helps to find the present day by using the now() or today() method.timedelta class from datetime module helps to find the previous day date and next day date.

Syntax for timedelta:

class datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)

For example, if the present date is 31th of December, incrementing the date directly will only lead to the 32nd of December which is false. If we want to manipulate the Date directly first we have check day month and year combined and them increment accordingly.

Syntax to find a present-day date:

datetime.now()

Returns: A datetime object containing the current local date and time.

Syntax to find a previous-day and next-day date:

previous-day = datetime.now()-timedelta(1)

next-day = datetime.now()+timedelta(1)

Example:

# Python program to find yesterday,
# today and tomorrow


# Import datetime and timedelta
# class from datetime module
from datetime import datetime, timedelta


# Get today's date
presentday = datetime.now() # or presentday = datetime.today()

# Get Yesterday
yesterday = presentday - timedelta(1)

# Get Tomorrow
tomorrow = presentday + timedelta(1)


# strftime() is to format date according to
# the need by converting them to string
print("Yesterday = ", yesterday.strftime('%d-%m-%Y'))
print("Today = ", presentday.strftime('%d-%m-%Y'))
print("Tomorrow = ", tomorrow.strftime('%d-%m-%Y'))

Output

Yesterday =  10-12-2019
Today =  11-12-2019
Tomorrow =  12-12-2019
