Hey everyone,

I’m working on a project where I need to calculate an employee’s salary based on their start date within a given month. I’m trying to determine the proportion of their salary for the month they started. Here’s a brief outline of what I’m doing, and I’d love to share my experience.

Here’s the approach I’m considering:

**Helper Variable**: I’m using the called`daysInMonth`

helper variable to keep track of the number of days in the start month.**Example Calculation**: Suppose an employee’s salary is $10,000 and they start in March. I want to compute the salary for the partial month they’ve worked.**Formula**: I’m planning to use the formula:

`if day = start month, then start_day/ days_in_month * salary`

.- In other words, for the start day, I’d calculate the proportion of the month worked as:

```
Proportion = (start_day / days_in_month)
```

- Then, apply this proportion to the salary to get:

```
Salary_for_start_month = Proportion * Salary
```

**Example**: If the start day is 10 in March (assuming March has 31 days), the calculation would be:

```
Proportion = 10 / 31
Salary_for_start_month = (10 / 31) * 10,000
```

Here’s an example for reference.
