How to add days to a variable date in twig

Question

A few days ago the need to add variables in twig, to be precise having a date for example: 2016-01-04 I need to add 540 days for this I use the date_modify plugin present in twig.

To perform this operation you must perform the following:

 {% In September modify = '540'%}
 {% In September date = "now" | date ( "m / d / Y")%}

 {{Date | date_modify ( "+" ~ ~ modify "day") | date ( "m / d / Y")}}

With this the result would be: 08/31/2017

Do you know another way?

Answer 1

{{ yourDate|date_modify("+1 day")|date("m/d/Y") }}

this code add 1 day to your date.
