Hi,

Could you please try to check the days count based on the given code

from datetime import date

date1 = date(2023, 1, 1)  # Assuming the first date is January 1, 2023
date2 = date(2023, 1, 10)  # Assuming the second date is January 10, 2023

delta = date2 - date1  # Calculate the time difference
days_between = delta.days  # Extract the number of days

and also Make sure that the elements in the datetime list are dictionaries or objects that support dictionary-like access using square brackets (record['x_farribo'] and record['x_age']). If you're using a different data structure, adapt the code accordingly. some times the datatypes error got this kind of error

Hope it helps
