Python program to find day of the week for a given date
Write a Python program to find the day of the week for any particular date in the past or future. Let the input be in the format “dd mm yyyy”.
Examples:
Input : 03 02 1997 Output : Monday Input : 31 01 2019 Output : Thursday
Approach #1 : Using weekday() provided by datetime module.
The weekday() function of date class in datetime module, returns an integer corresponding to the day of the week.
- Python3
# Python program to Find day of# the week for a given dateimport datetimeimport calendardef findDay(date): born = datetime.datetime.strptime(date, '%d %m %Y').weekday() return (calendar.day_name[born])# Driver programdate = '03 02 2019'print(findDay(date)) |
Output:
Sunday
Approach #2 : Using strftime() method
The strftime() method takes one or more format codes as an argument and returns a formatted string based on it. Here we will pass the directive “%A” in the method which provides Full weekday name for the given date.
- Python3
# Python program to Find day of# the week for a given dateimport datetimefrom datetime import dateimport calendardef findDay(date): day, month, year = (int(i) for i in date.split(' ')) born = datetime.date(year, month, day) return born.strftime("%A")# Driver programdate = '03 02 2019'print(findDay(date)) |
Output:
Sunday
Approach #3 : By finding day number
In this approach, we find the day number using calendar module and then find the corresponding week day.
- Python3
# Python program to Find day of# the week for a given dateimport calendardef findDay(date): day, month, year = (int(i) for i in date.split(' ')) dayNumber = calendar.weekday(year, month, day) days =["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"] return (days[dayNumber])# Driver programdate = '03 02 2019'print(findDay(date)) |
Output:
Sunday
