Calculate future date

Question

I want to calculate a future date based on the date the post is published and use it in the content of a post.

I can echo the post publication date using:

echo the_date('Y-m-d');

How can I calculate the future date?

Answer 1

try

$future_timestamp = strtotime('+1 week', get_the_date('Y-m-d'));

echo date('Y-m-d', $future_timestamp);

or

$future_timestamp = get_the_date('U') + (60 * 60 * 24 * 7);

echo date('Y-m-d', $future_timestamp);
