Formatting Date and Time

Customizing the Time and Date

Certain WordPress tag functions are used to display or return date and time information;

the_date() and
the_time() are examples of this. Some of these functions accept a parameter called a format string that allows you to determine how the date is going to be displayed. The format string is a template in which various parts of the date are combined (using
"format characters") to generate a date in the format specified.

For example, the format string:

l, F j, Y

creates a date that look like this:

Friday, September 24, 2004

Here is what each format character in the string above represents:

l

= Full name for day of the week (lower-case L).

F

= Full name for the month.

j

= The day of the month.

Y

= The year in 4 digits. (lower-case y gives the year's last 2 digits)

(Commas are read literally.)
WordPress is written in the programming language
PHP. The date formatting functions in WordPress use PHP's built-in date formatting functions. You can use the
table of date format characters on the PHP website as a reference for building date format strings for use in WordPress. Here is a table of some of the more useful items found
there:

Day of Month
d	Numeric, with leading zeros	01–31
j	Numeric, without leading zeros	1–31
S	The English suffix for the day of the month	st, nd or th in the 1st, 2nd or 15th.
Weekday
l	Full name (lowercase 'L')	Sunday – Saturday
D	Three letter name	Mon – Sun
Month
m	Numeric, with leading zeros	01–12
n	Numeric, without leading zeros	1–12
F	Textual full	January – December
M	Textual three letters	Jan - Dec
Year
Y	Numeric, 4 digits	Eg., 1999, 2003
y	Numeric, 2 digits	Eg., 99, 03
Time
a	Lowercase	am, pm
A	Uppercase	AM, PM
g	Hour, 12-hour, without leading zeros	1–12
h	Hour, 12-hour, with leading zeros	01–12

H	Hour, 24-hour, with leading zeros	00-23
i	Minutes, with leading zeros	00-59

Examples

Here are some examples of date format and result output.

F j, Y g:i a

- November 6, 2010 12:50 am

F j, Y

- November 6, 2010

M j, Y @ G:i

- Nov 6, 2010 @ 0:50

Y/m/d \a\t g:i A

This entry was posted on <?php the_time('l, F jS, Y') ?> and is filed under <?php the_category(', ') ?>.

Localization

To localize dates, use the
date_i18n() function.

You can probably safely localize these date format strings with the

__()

,

_e()

, etc. functions (demonstrated with

get_the_date(__(…))

):
