Anchor
_date
_date
date

The date filter is used to format an existing java.util.Date object. The filter will construct a java.text.SimpleDateFormat using the provided pattern and then use this newly created SimpleDateFormat to format the provided Date object.
The alternative way to use this filter is to use it on a string but then provide two arguments. The first is the desired pattern for the output and the second is the existing format used to parse the input string into a java.util.Date object.

Example : If todayDate is a java.util.Date object

{{ todayDate

 | date("yyyy-MM-dd") }}

Output

2017-12-25


Example 2

{{ "December 25, 2017"

 | date("yyyy-MM-dd", existingFormat="MMMM dd, yyyy") }}

Output

2017-12-25
