The date function has a z format character, which can be used for this:

$day_of_year = date('z');
// $day_of_year is 259 for the day I write this

If you were interested in the name of the first day of the year 

echo date('l', strtotime('2012-01-01'));

OR 

echo date('l', strtotime("first day of January 2012"));

Output:// Sunday

OR

just use -

echo (date('z') === 0) ? 'First day' : 'Not first day';

//z     The day of the year (starting from 0)   0 through 365

This should solve your problem and more!

<?php
$theDate = date("md"); 
if ($theDate=="0101") echo "It's A New Year!";
?>

Date() function formatting characters:

  • d - A numeric representation of the day of the month (0 - 31)
  • m - A numeric representation of the month of the year (1 - 12)
  • y - A numeric representation (two digit) of a year (99, 00, 01, 02)
  • H - 24 hour format current hour (00 - 23)
  • i - Minutes (00 - 59)
  • s - Seconds (00 - 59)

The first day of the year is never different from 1/1/yyyy You can use strcmp or 

$now=new DateTime();

then use getDay GetMonth from $now to evaluate

You can get the day of the year by passing the format string 'z' do the built-in date() function. This will return '0' for the first day, '1' for the second, ... up to '365' for the last day of a (leap) year.

if ( date('z') === '0' ) {
    //Today is the first day of the year.
}

if(date('j') == '1' && date('n') == 1){
    // if first day of year
}

That will do it easily without any complicated date stuff that you would normally have to worry about.
