RECOGNIZED CHARACTERS
format character Description Example
returned values
Day
d Day of the month, 2 digits with leading zeros 01 to 31
D A textual representation of a day, three letters Mon through Sun

through
Saturday
N ISO-8601 numeric representation of the day of the week
Since PHP 5.1.0		 1 (for Monday)
through
7 (for Sunday)
S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th.
Works well with j
w Numeric representation of the day of the week 0 (for Sunday)
through
6 (for Saturday)
z The day of the year (starting from 0) 0 through 365
Week
W ISO-8601 week number of year, weeks starting on Monday Example:

through
December
m Numeric representation of a month, with leading zeros 01 through 12
M A short textual representation of a month, three letters Jan through Dec
n Numeric representation of a month, without leading zeros 1 through 12
t Number of days in the given month 28 through 31
Year
L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
o ISO-8601 week-numbering year.
This has the same value as Y,
except that if the ISO week number (W) belongs to the previous or next year, that year is used instead.
Since PHP 5.1.0		 Examples:
1999 or 2018
Y A full numeric representation of a year, 4 digits Examples:
1999 or 2018
y A two digit representation of a year Examples:
99 or 18
Time
a Lowercase Ante meridiem and Post meridiem am or pm
A Uppercase Ante meridiem and Post meridiem AM or PM
B Swatch Internet time 000 through 999
g 12-hour format of an hour without leading zeros 1 through 12
G 24-hour format of an hour without leading zeros 0 through 23
h 12-hour format of an hour with leading zeros 01 through 12
H 24-hour format of an hour with leading zeros 00 through 23
i Minutes with leading zeros 00 to 59
s Seconds, with leading zeros 00 through 59
u Microseconds - Since PHP 5.2.2.
Note that date_format will always generate 000000
since it takes an integer parameter,
whereas date_formatTime::format does
support microseconds if date_formatTime created with microseconds. 		Example: 654321
v Milliseconds - Since PHP 7.0.0.
Same note applies as for u. 		Example: 654
Timezone
e Timezone identifier
Since PHP 5.1.0		 Examples: UTC, GMT, Atlantic/Azores
I (capital i) Whether or not the date_format is in Daylight Saving Time 1 if DST, 0 if not DST.
O Difference to Greenwich time (GMT) in hours Example: +0200
P Difference to Greenwich time (GMT)
with colon between hours and minutes.
Since PHP 5.1.3		 Example: +02:00
p The same as P, but returns Z instead of +00:00 Example: +02:00
T Timezone abbreviation Examples: EST, MDT ...
Z Timezone offset in seconds.
The offset for timezones west of UTC
is always negative,
and for those east of UTC is always positive.		 -43200 through 50400
Full date_format/Time
c ISO 8601 date_format (added in PHP 5) 2004-02-12T15:
