# Date

The Date Data Type is used to represent a calendar date. A Date consists of three sets of numbers representing a year, month, and day. The year is represented directly, for example **2021** is the year 2021. The month is a Number ranging from one to twelve. One represents January, whereas twelve represents December. The day represents which day in the calendar month the date occurs on starting from one, in other words a day with the value **1** represents the first day of that month.

Dates can be created using the **DATE** function which takes the year, month, and day as arguments. For example a Date for September 18th, 2017 can be created by calling the Date function with the arguments **2017**, **9**, **18** respectively.

```javascript
DATE(2017, 9, 18) -> {"day": 18,  
    "month": 9,  
    "year": 2017 } 
```
