String Format for DateTime [C#]
This example shows how to format Date Time using String.Format method. All formatting can be done also using DateTime.ToString method.
Custom DateTime Formatting
You can use also date separator
Here are some examples of custom date and time formatting:[C#]
Custom DateTime Formatting
There are following custom format specifiers
y
(year), M
(month), d
(day), h
(hour 12), H
(hour 24), m
(minute), s
(second), f
(second fraction), F
(second fraction, trailing zeroes are trimmed),t
(P.M or A.M) and z
(time zone).Following examples demonstrate how are the format specifiers rewritten to the output.[C#]
// create date time 2008-03-09 16:05:07.123 DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123); String.Format("{0:y yy yyy yyyy}", dt); // "8 08 008 2008" year String.Format("{0:M MM MMM MMMM}", dt); // "3 03 Mar March" month String.Format("{0:d dd ddd dddd}", dt); // "9 09 Sun Sunday" day String.Format("{0:h hh H HH}", dt); // "4 04 16 16" hour 12/24 String.Format("{0:m mm}", dt); // "5 05" minute String.Format("{0:s ss}", dt); // "7 07" second String.Format("{0:f ff fff ffff}", dt); // "1 12 123 1230" sec.fraction String.Format("{0:F FF FFF FFFF}", dt); // "1 12 123 123" without zeroes String.Format("{0:t tt}", dt); // "P PM" A.M. or P.M. String.Format("{0:z zz zzz}", dt); // "-6 -06 -06:00" time zone
You can use also date separator
/
(slash) and time sepatator :
(colon). These characters will be rewritten to characters defined in the current DateTimeFormatInfo.DateSeparator andDateTimeFormatInfo.TimeSeparator.[C#]// date separator in german culture is "." (so "/" changes to ".") String.Format("{0:d/M/yyyy HH:mm:ss}", dt); // "9/3/2008 16:05:07" - english (en-US) String.Format("{0:d/M/yyyy HH:mm:ss}", dt); // "9.3.2008 16:05:07" - german (de-DE)
Here are some examples of custom date and time formatting:[C#]
// month/day numbers without/with leading zeroes String.Format("{0:M/d/yyyy}", dt);// "3/9/2008" String.Format("{0:MM/dd/yyyy}", dt);// "03/09/2008" // day/month names String.Format("{0:ddd, MMM d, yyyy}", dt);// "Sun, Mar 9, 2008" String.Format("{0:dddd, MMMM d, yyyy}", dt);// "Sunday, March 9, 2008" // two/four digit year String.Format("{0:MM/dd/yy}", dt);// "03/09/08" String.Format("{0:MM/dd/yyyy}", dt);// "03/09/2008"
Standard DateTime Formatting
In DateTimeFormatInfo there are defined standard patterns for the current culture. For example property ShortTimePattern is string that contains value
h:mm tt
for en-US culture and value HH:mm
for de-DE culture.Following table shows patterns defined in DateTimeFormatInfo and their values for en-US culture. First column contains format specifiers for the String.Format method.
Specifier | DateTimeFormatInfo property | Pattern value (for en-US culture) |
---|---|---|
t | ShortTimePattern | h:mm tt |
d | ShortDatePattern | M/d/yyyy |
T | LongTimePattern | h:mm:ss tt |
D | LongDatePattern | dddd, MMMM dd, yyyy |
f | (combination of D and t ) | dddd, MMMM dd, yyyy h:mm tt |
F | FullDateTimePattern | dddd, MMMM dd, yyyy h:mm:ss tt |
g | (combination of d and t ) | M/d/yyyy h:mm tt |
G | (combination of d and T ) | M/d/yyyy h:mm:ss tt |
m , M | MonthDayPattern | MMMM dd |
y , Y | YearMonthPattern | MMMM, yyyy |
r , R | RFC1123Pattern | ddd, dd MMM yyyy HH':'mm':'ss 'GMT' (*) |
s | SortableDateTimePattern | yyyy'-'MM'-'dd'T'HH':'mm':'ss (*) |
u | UniversalSortableDateTimePattern | yyyy'-'MM'-'dd HH':'mm':'ss'Z' (*) |
(*) = culture independent |
Following examples show usage of standard format specifiers in String.Format method and the resulting output.
[C#]String.Format("{0:t}", dt); // "4:05 PM" ShortTime String.Format("{0:d}", dt); // "3/9/2008" ShortDate String.Format("{0:T}", dt); // "4:05:07 PM" LongTime String.Format("{0:D}", dt); // "Sunday, March 09, 2008" LongDate String.Format("{0:f}", dt); // "Sunday, March 09, 2008 4:05 PM" LongDate+ShortTime String.Format("{0:F}", dt); // "Sunday, March 09, 2008 4:05:07 PM" FullDateTime String.Format("{0:g}", dt); // "3/9/2008 4:05 PM" ShortDate+ShortTime String.Format("{0:G}", dt); // "3/9/2008 4:05:07 PM" ShortDate+LongTime String.Format("{0:m}", dt); // "March 09" MonthDay String.Format("{0:y}", dt); // "March, 2008" YearMonth String.Format("{0:r}", dt); // "Sun, 09 Mar 2008 16:05:07 GMT" RFC1123 String.Format("{0:s}", dt); // "2008-03-09T16:05:07" SortableDateTime String.Format("{0:u}", dt); // "2008-03-09 16:05:07Z" UniversalSortableDateTime
