Calculate time offset in days - part 1

Calculating time offset for each transaction allows you to report the metrics for each cohort in a comparable fashion.

First, we will create 6 variables that capture the integer value of years, months and days for Invoice and Cohort Date using the get_date_int() function that's been already defined for you:

def get_date_int(df, column):
    year = df[column].dt.year
    month = df[column].dt.month
    day = df[column].dt.day
    return year, month, day

The online data has been loaded, you can print its header to the console by calling online.head().

Create invoice_year, invoice_month, invoice_day objects by calling get_date_int function on InvoiceDay column.
Create cohort_year, cohort_month, cohort_day objects by calling get_date_int function on CohortDay column.
