d	Day of the month, 2 digits with leading zeros	01 to 31
j	Day of the month without leading zeros	1 to 31
S	English ordinal suffix for the day of the month, 2 characters	st, nd, rd or th
F	A full textual representation of a month, such as January or March	January to December

Y	A full numeric representation of a year, 4 digits	Examples: 1988 or 2017

When a $format is not given its default value is Y-m-d.
