# isWorkDay


`isWorkDay` evaluates a given date-time value to determine if the value is a workday or not.

`isWorkDay` assumes a standard 5-day work week starting from Monday and ending on Friday. Saturday and Sunday are assumed to be weekends. The function always calculates its result at the `DAY` granularity and is exclusive of the given input date.

## Syntax


```
isWorkDay(inputDate)
```

## Arguments


 *inputDate*   
The date-time value that you want to evaluate. Valid values are as follows:  
+ Dataset fields: Any `date` field from the dataset that you are adding this function to.
+ Date Functions: Any date output from another `date` function, for example, `parseDate`.
+ Calculated fields: Any Quick calculated field that returns a `date` value.
+ Parameters: Any Quick `DateTime` parameter.

## Return type


Integer (`0` or `1`)

## Example


The following exaple determines whether or not the `application_date` field is a work day.

Let's assume that there's a field named `application_date` with the following values:

```
2022-08-10 
2022-08-06 
2022-08-07
```

When you use these fields and add the following calculations, `isWorkDay` returns the below values:

```
isWorkDay({application_date})     
                                                     
1
0
0
```

The following example filters employees whose employment ends on a work day and determines whether their employment began on work day or a weekend using conditional formatting:

```
is_start_date_work_day = isWorkDay(employment_start_date)
is_end_date_work_day = isWorkDay(employment_end_date)
```
