PHP Date Formatting

m.d.y01.23.21Simple with leading zeros
l, F jS G:i:sSaturday, January 23rd 3:47:59Day, date, and 24-hour (military) time
D M jSat Jan 23Short versions of day and month
n/j g:i A1/23 3:47 AMDate without leading zeros and AM/PM in uppercase
Y: \D\a\y #z2021: Day #22Day of the year (0-365)
