. Methods, fields, and other functionality specific to ICU are labeled '[icu]'.
DateFormat is an abstract class for date/time formatting subclasses which formats and parses dates or time in a language-independent manner. The date/time formatting subclass, such as SimpleDateFormat, allows for formatting (i.e., date -> text), parsing (text -> date), and normalization. The date is represented as a Date
object or as the milliseconds since January 1, 1970, 00:00:00 GMT.
DateFormat helps you to format and parse dates for any locale. Your code can be completely independent of the locale conventions for months, days of the week, or even the calendar format: lunar vs. solar. It provides many class methods for obtaining default date/time formatters based on the default for a given locale and a number of formatting styles or arbitrary "skeletons".
- The formatting styles include FULL, LONG, MEDIUM, and SHORT. More detail and examples of using these styles are provided in the method descriptions.
- The formatting styles only cover a fraction of the necessary usage. You often need to have just certain combinations of fields, like Month and Year, but have it to be formatted appropriate to a given locale. This is done using the (misnamed) getPatternInstance() method, supplying a skeleton. There are a number of constants that have common pre-defined skeletons, such as
MINUTE_SECOND
for something like "13:45" orYEAR_ABBR_MONTH
for something like "Sept 2012".
To format a date for the current Locale, use one of the static factory methods:
myString = DateFormat.getDateInstance().format(myDate); myString = DateFormat.getPatternInstance(DateFormat.YEAR_ABBR_MONTH).format(myDate);
If you are formatting multiple numbers, it is more efficient to get the format and use it multiple times so that the system doesn't have to fetch the information about the local language and country conventions multiple times.
DateFormat df = DateFormat.getDateInstance(); for (int i = 0; i < a.length; ++i) { output.println(df.format(myDate[i]) + "; "); }
To format a date for a different Locale, specify it in the call to getDateInstance().
DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
You can use a DateFormat to parse also.
myDate = df.parse(myString);
There are many static factory methods available. Use getDateInstance to get the normal date format for that country. Use getTimeInstance to get the time format for that country. Use getDateTimeInstance to get a date and time format. You can pass in different options to these factory methods to control the length of the result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the locale, but generally:
- SHORT is completely numeric, such as 12.13.52 or 3:30pm
- MEDIUM is longer, such as Jan 12, 1952
- LONG is longer, such as January 12, 1952 or 3:30:32pm
- FULL is pretty completely specified, such as Tuesday, April 12, 1952 AD or 3:30:42pm PST.
Use getPatternInstance to format with a skeleton. Typically this is with a predefined skeleton, like YEAR_ABBR_MONTH
for something like "Sept 2012". If you don't want to use one of the predefined skeletons, you can supply your own. The skeletons are like the patterns in SimpleDateFormat, except they:
- only keep the field pattern letter and ignore all other parts in a pattern, such as space, punctuation, and string literals.
- are independent of the order of fields.
- ignore certain differences in the field's pattern letter length:
- For those non-digit calendar fields, the pattern letter length is important, such as MMM, MMMM, and MMMMM; E and EEEE, and the field's pattern letter length is honored.
- For the digit calendar fields, such as M or MM, d or dd, yy or yyyy, the field pattern length is ignored and the best match, which is defined in date time patterns, will be returned without honor the field pattern letter length in skeleton.
You can also set the time zone on the format if you wish. If you want even more control over the format or parsing, (or want to give your users more control), you can try casting the DateFormat you get from the factory methods to a SimpleDateFormat. This will work for the majority of countries; just remember to put it in a try block in case you encounter an unusual one.
You can also use forms of the parse and format methods with ParsePosition and FieldPosition to allow you to
- progressively parse through pieces of a string.
- align any particular field, or find out where it is for selection on the screen.
Synchronization
Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally.Summary

parse
open fun parse(text: String!): Date!
Parses a date/time string. For example, a time text "07/10/96 4:5 PM, PDT" will be parsed into a Date that is equivalent to Date(837039928046). Parsing begins at the beginning of the string and proceeds as far as possible. Assuming no parse errors were encountered, this function doesn't return any information about how much of the string was consumed by the parsing. If you need that information, use a version of parse() that takes a ParsePosition.
By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).
Note that the normal date formats associated with some calendars - such as the Chinese lunar calendar - do not specify enough fields to enable dates to be parsed unambiguously. In the case of the Chinese lunar calendar, while the year within the current 60-year cycle is specified, the number of such cycles since the start date of the calendar (in the ERA field of the Calendar object) is not normally part of the format, and parsing may assume the wrong era. For cases such as this it is recommended that clients parse using the parse method that takes a Calendar with the Calendar passed in set to the current date, or to a date within the era/cycle that should be assumed if absent in the format.
Parameters | |
---|---|
text |
String!: The date/time string to be parsed |
Return | |
---|---|
Date! |
A Date, or null if the input could not be parsed |
Exceptions | |
---|---|
java.text.ParseException |
If the given string cannot be parsed as a date. |

parse
abstract fun parse(
text: String!,
cal: Calendar!,
pos: ParsePosition!
): Unit
Parses a date/time string according to the given parse position. For example, a time text "07/10/96 4:5 PM, PDT" will be parsed into a Calendar that is equivalent to Date(837039928046). Before calling this method the caller should initialize the calendar in one of two ways (unless existing field information is to be kept): (1) clear the calendar, or (2) set the calendar to the current date (or to any date whose fields should be used to supply values that are missing in the parsed date). For example, Chinese calendar dates do not normally provide an era/cycle; in this case the calendar that is passed in should be set to a date within the era that should be assumed, normally the current era.
By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).
Parameters | |
---|---|
text |
String!: The date/time string to be parsed |
cal |
Calendar!: The calendar set on input to the date and time to be used for missing values in the date/time string being parsed, and set on output to the parsed date/time. In general, this should be initialized before calling this method - either cleared or set to the current date, depending on desired behavior. If this parse fails, the calendar may still have been modified. When the calendar type is different from the internal calendar held by this DateFormat instance, calendar field values will be parsed based on the internal calendar initialized with the time and the time zone taken from this calendar, then the parse result (time in milliseconds and time zone) will be set back to this calendar. |
pos |
ParsePosition!: On input, the position at which to start parsing; on output, the position at which parsing terminated, or the start position if the parse failed. |

parse
open fun parse(
text: String!,
pos: ParsePosition!
): Date!
Parses a date/time string according to the given parse position. For example, a time text "07/10/96 4:5 PM, PDT" will be parsed into a Date that is equivalent to Date(837039928046).
By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).

Parameters | |
---|---|
text |
String!: The date/time string to be parsed |
pos |
ParsePosition!: On input, the position at which to start parsing; on output, the position at which parsing terminated, or the start position if the parse failed. |
Return | |
---|---|
Date! |
A Date, or null if the input could not be parsed |

parseObject
open fun parseObject(
source: String!,
pos: ParsePosition!
): Any!
Parses a date/time string into an Object. This convenience method simply calls parse(String, ParsePosition).
Parameters | |
---|---|
source |
String!: A String , part of which should be parsed. |
pos |
ParsePosition!: A ParsePosition object with index and error index information as described above. |
Return | |
---|---|
Any! |
An Object parsed from the string. In case of error, returns null. |
Exceptions | |
---|---|
java.lang.NullPointerException |
if source or pos is null. |

setBooleanAttribute
open fun setBooleanAttribute(
key: DateFormat.BooleanAttribute!,
value: Boolean
): DateFormat!
Sets a boolean attribute for this instance. Aspects of DateFormat leniency are controlled by boolean attributes.
setCalendar
open fun setCalendar(newCalendar: Calendar!): Unit
Sets the calendar to be used by this date format. Initially, the default calendar for the specified or default locale is used.
Parameters | |
---|---|
newCalendar |
Calendar!: the new Calendar to be used by the date format |
setCalendarLenient
open fun setCalendarLenient(lenient: Boolean): Unit
Specifies whether date/time parsing in the encapsulated Calendar object should be lenient. With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. Without lenient parsing, inputs must match this object's format more closely.
Parameters | |
---|---|
lenient |
Boolean: when true, Calendar parsing is lenient |
See Also
setContext
open fun setContext(context: DisplayContext!): Unit
[icu] Set a particular DisplayContext value in the formatter, such as CAPITALIZATION_FOR_STANDALONE.
Parameters | |
---|---|
context |
DisplayContext!: The DisplayContext value to set. |
setLenient
open fun setLenient(lenient: Boolean): Unit
Specifies whether date/time parsing is to be lenient. With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. Without lenient parsing, inputs must match this object's format more closely.
Note: ICU 53 introduced finer grained control of leniency (and added new control points) making the preferred method a combination of setCalendarLenient() & setBooleanAttribute() calls. This method supports prior functionality but may not support all future leniency control & behavior of DateFormat. For control of pre 53 leniency, Calendar and DateFormat whitespace & numeric tolerance, this method is safe to use. However, mixing leniency control via this method and modification of the newer attributes via setBooleanAttribute() may produce undesirable results.
Parameters | |
---|---|
lenient |
Boolean: True specifies date/time interpretation to be lenient. |
setNumberFormat
open fun setNumberFormat(newNumberFormat: NumberFormat!): Unit
Sets the number formatter.
Parameters | |
---|---|

NumberFormat!: the given new NumberFormat. |
setTimeZone
open fun setTimeZone(zone: TimeZone!): Unit
Sets the time zone for the calendar of this DateFormat object.
Parameters | |
---|---|
zone |
TimeZone!: the given new time zone. |
