## Calculating the Difference Between Two Dates in Linx (Handling Leap Years)

When working with date calculations in Linx, especially for determining the **difference between two dates** , it’s important to ensure your approach is both accurate and robust to all calendar scenarios—such as leap years.

_Note that this approach will give you the difference between to dates in days_

**While some solutions manually add days based on year or month differences, this can easily introduce errors, especially when dealing with leap years or months of varying lengths.**

**The recommended method in Linx is to use the built-in expression editor to subtract one `DateTime` value from another:**

```csharp
(DateTimeEnd - DateTimeStart).Days

```

This expression will return the **exact number of days** between the two dates, and it will correctly include or exclude February 29th in leap years and handle all other irregularities in the calendar for you.

> **Note:**  
> This approach requires that both values (`DateTimeStart` and `DateTimeEnd`) are already of the `DateTime` type. If your source data is already stored as `DateTime` values (passed in as parameters or already defined as such in your process), you’re good to go—no extra parsing or conversion needed!

### Example

Here you can see the calculation done with no leap year dates:

And here is the calculation done with dates that are part of a leap year:

### Summary

- Use `(DateTimeEnd - DateTimeStart).Days` for a safe, leap-year aware calculation.
- Ensure both inputs are of type `DateTime`.

This will provide you with a simple, accurate, and future-proof date difference calculation in Linx.
