Building a custom DateTime.ToString Patterns

The following details the meaning of each pattern character. Note the K and z character.

d

Represents the day of the month as a number from 1 through 31. A single-digit day is
formatted without a leading zero

dd

Represents the day of the month as a number from 01 through 31. A single-digit day is
formatted with a leading zero

ddd

Represents the abbreviated name of the day of the week (Mon, Tues, Wed etc)

dddd

Represents the full name of the day of the week (Monday, Tuesday etc)

h

12-hour clock hour (e.g. 7)

hh

12-hour clock, with a leading 0 (e.g. 07)

H

24-hour clock hour (e.g. 19)

HH

24-hour clock hour, with a leading 0 (e.g. 19)

m

Minutes

mm

Minutes with a leading zero

M

Month number

MM

Month number with leading zero

MMM

Abbreviated Month Name (e.g. Dec)

MMMM

Full month name (e.g. December)

s

Seconds

ss

Seconds with leading zero

t

Abbreviated AM / PM (e.g. A or P)

tt

AM / PM (e.g. AM or PM

y

Year, no leading zero (e.g. 2001 would be 1)

yy

Year, leadin zero (e.g. 2001 would be 01)

yyy

Year, (e.g. 2001 would be 2001)

yyyy

Year, (e.g. 2001 would be 2001)

K

Represents the time zone information of a date and time value (e.g. +05:00)

z

With DateTime values, represents the signed offset of the local operating system's time zone
from Coordinated Universal Time (UTC), measured in hours. (e.g. +6)

zz

As z but with leadin zero (e.g. +06)

zzz

With DateTime values, represents the signed offset of the local operating system's time zone
from UTC, measured in hours and minutes. (e.g. +06:00)

f

Represents the most significant digit of the seconds fraction; that is, it represents the tenths of
a second in a date and time value.

ff

Represents the two most significant digits of the seconds fraction; that is, it represents the
hundredths of a second in a date and time value.

fff

Represents the three most significant digits of the seconds fraction; that is, it represents the
milliseconds in a date and time value.

ffff

Represents the four most significant digits of the seconds fraction; that is, it represents the ten
thousandths of a second in a date and time value. While it is possible to display the ten
thousandths of a second component of a time value, that value may not be meaningful.
The precision of date and time values depends on the resolution of the system clock. On
Windows NT 3.5 and later, and Windows Vista operating systems, the clock's resolution is
approximately 10-15 milliseconds.

fffff

Represents the five most significant digits of the seconds fraction; that is, it represents the
hundred thousandths of a second in a date and time value. While it is possible to display the
hundred thousandths of a second component of a time value, that value may not be meaningful.

The precision of date and time values depends on the resolution of the system clock. On
Windows NT 3.5 and later, and Windows Vista operating systems, the clock's resolution is
approximately 10-15 milliseconds.

ffffff

Represents the six most significant digits of the seconds fraction; that is, it represents the millionths
of a second in a date and time value. While it is possible to display the millionths of a second
component of a time value, that value may not be meaningful. The precision of date and time
values depends on the resolution of the system clock. On Windows NT 3.5 and later, and
Windows Vista operating systems, the clock's resolution is approximately 10-15 milliseconds.

fffffff

Represents the seven most significant digits of the seconds fraction; that is, it represents the ten
millionths of a second in a date and time value. While it is possible to display the ten millionths
of a second component of a time value, that value may not be meaningful. The precision of
date and time values depends on the resolution of the system clock. On Windows NT 3.5
and later, and Windows Vista operating systems, the clock's resolution is approximately
10-15 milliseconds.

F

Represents the most significant digit of the seconds fraction; that is, it represents the tenths
of a second in a date and time value. Nothing is displayed if the digit is zero.

:

Represents the time separator defined in the current DateTimeFormatInfo..::.TimeSeparator
property. This separator is used to differentiate hours, minutes, and seconds.

/

Represents the date separator defined in the current DateTimeFormatInfo..::.
DateSeparator property. This separator is used to differentiate years, months, and days.

"

Represents a quoted string (quotation mark). Displays the literal value of any string between
two quotation marks ("). Your application should precede each quotation mark with an escape
character (\).

'

Represents a quoted string (apostrophe). Displays the literal value of any string between two
apostrophe (') characters.

%c

Represents the result associated with a c custom format specifier, when the custom date and
time format string consists solely of that custom format specifier. That is, to use the d, f, F, h,
m, s, t, y, z, H, or M custom format specifier by itself, the application should specify %d, %f,
%F, %h, %m, %s, %t, %y, %z, %H, or %M. For more information about using a single format
specifier, see Using Single Custom Format Specifiers.

||\c || Represents the escape character, and displays the character "c" as a literal when that character is
preceded by the escape character (\). To insert the backslash character itself in the result string, the application
should use two escape characters ("\\").
