 * Hi everybody,
 * I want to write someone’s age and I want it to be dynamic. So let’s say Julie
   is 20 years old. Then Julie is (this year – 1981) years old.
 * I manage to do that calculation on WP with the following code:
 *     ```
       <?php $prodid = 2011;
       $second_number = 1991;
       $sum_total = $prodid - $second_number;
       print ($sum_total);
       ?>
       ```
   
 * But it’s still not dynamic – I’d like the 2011 to be <?php the_time(‘Y’); ?> 
   but it’s doesn’t work!!! ^
    Can someone help me with this detail?
 * [s]

 * `$prodid = strftime('%Y');`

 * `print(idate('Y')-$second_number);`
