Get start date and end date of the week, given week number and year

Question

How do I get the start date and end date of the week, given week number and year in python?

I\'ve tried this:

def get_start_end_dates(year, week):

          


        

Answer 1

I have fixed your function:

def get_start_end_dates(year, week):
     d = date(year,1,1)
     if(d.weekday()<= 3):
         d = d - timedelta(d.weekday())             
     else:
         d = d + timedelta(7-d.weekday())
     dlt = timedelta(days = (week-1)*7)
     return d + dlt,  d + dlt + timedelta(days=6)

It gets the correct start and end day of the week in given year.

It also assumes that years with first day of the year on Friday, Saturday or Sunday have 1 week on next week. See here: http://en.wikipedia.org/wiki/Week

Answer 2

import datetime
import time

 def getDateRangeFromWeek(p_year,p_week):

    firstdayofweek = datetime.datetime.strptime(f'{p_year}-W{int(p_week )- 1}-1', "%Y-W%W-%w").date()
    lastdayofweek = firstdayofweek + datetime.timedelta(days=6.9)
    return firstdayofweek, lastdayofweek


#Call function to get dates range 
firstdate, lastdate =  getDateRangeFromWeek('2019','2')

print('print function ',firstdate,' ', lastdate)
