Handling Leap Year Calculations in Python's datetime Module for Financial Reporting
I'm trying to configure I need help solving Hey everyone, I'm running into an issue that's driving me crazy..... I am currently working on a financial reporting system in Python that relies on accurate date calculations. I need to account for leap years when determining the end of a fiscal year, which runs from April 1 to March 31. However, I've run into an scenario when trying to calculate the end date of the fiscal year for the year 2024. Using the built-in `datetime` module, I wrote the following code: ```python from datetime import datetime, timedelta # Define the start of the fiscal year fiscal_start = datetime(2024, 4, 1) # Calculate the end of the fiscal year fiscal_end = datetime(fiscal_start.year + 1, 4, 1) - timedelta(days=1) print(fiscal_end) ``` This code correctly outputs `2025-03-31 00:00:00`, which I expect. However, when I try to generalize this to check if the start date is in a leap year or not, using the `calendar` module, I face unexpected behavior: ```python import calendar # Check if the year is a leap year is_leap = calendar.isleap(fiscal_start.year) print(is_leap) ``` This returns `True`, as expected for 2024, but when I run similar code to handle fiscal years for different scenarios, the calculations sometimes yield the wrong end dates if I don't account for the leap year correctly. For example, if the fiscal start date is `2023-04-01`, and I want to calculate the end date for `2024`, the logic fails. I have tried different approaches to handle this, including manually adjusting the date calculations based on the year being a leap year, but it leads to more complexity and errors. I want a clean solution that correctly handles fiscal year end dates across leap years without introducing unnecessary complexity. Any suggestions or best practices for effectively managing leap years in date calculations within this context would be greatly appreciated! I'm working on a API that needs to handle this. Thanks in advance! This is for a web app running on Windows 10. Any help would be greatly appreciated! I've been using Python for about a year now. What's the correct way to implement this?
