Help re PHP date function and help website

Hello. I'm looking at the php date function. easy enough. https://www.php.net/manual/en/function.date.php However Question:- where is the help page to tell us what all the various letters mean ? January (month in full) Jan (small month ) etc... i remember this from somewhere but i cant find it on the above page. QUESTION: How do we ask / recommend that the page be amended ? -0 to add all the letters & meanings, or add a link to the page that tells us that ? Question- what are the letters for a full month, and big month ? ADMIN:- can the 'help' email command be added at the bottom of each message ? php-general-help@lists.php.net - took me 20 mins to find / try it, -- Gordon.
