I have used the India localization for the payroll. In order to calculate the "Basic" component, I need to dynamically calculate the number of days in the month in the formula. The rest of the "earnings" and "deductions" are based off of "Basic".

Unfortunately the Python code formula created out of the box in Version 17 of Odoo is incorrect. 

Please can someone help me calculate the number of working days in a month - dynamically?

Thank you!
