*** ** * ** ***
`Calendar.Builder`is used for creating a`Calendar`from various date-time parameters.
There are two ways to set a`Calendar`to a date-time value. One is to set the instant parameter to a millisecond offset from the[Epoch](https://developer.android.com/reference/java/util/Calendar#Epoch). The other is to set individual field parameters, such as[YEAR](https://developer.android.com/reference/java/util/Calendar#YEAR), to their desired values. These two ways can't be mixed. Trying to set both the instant and individual fields will cause an[IllegalStateException](https://developer.android.com/reference/java/lang/IllegalStateException)to be thrown. However, it is permitted to override previous values of the instant or field parameters.
If no enough field parameters are given for determining date and/or time, calendar specific default values are used when building a`Calendar`. For example, if the[YEAR](https://developer.android.com/reference/java/util/Calendar#YEAR)value isn't given for the Gregorian calendar, 1970 will be used. If there are any conflicts among field parameters, the[resolution rules](https://developer.android.com/reference/java/util/Calendar#resolution)are applied. Therefore, the order of field setting matters.
In addition to the date-time parameters, the[locale](https://developer.android.com/reference/java/util/Calendar.Builder#setLocale(java.util.Locale)),[time zone](https://developer.android.com/reference/java/util/Calendar.Builder#setTimeZone(java.util.TimeZone)),[week definition](https://developer.android.com/reference/java/util/Calendar.Builder#setWeekDefinition(int,%20int)), and[leniency mode](https://developer.android.com/reference/java/util/Calendar.Builder#setLenient(boolean))parameters can be set.
**Examples**
The following are sample usages. Sample code assumes that the`Calendar`constants are statically imported.
The following code produces a`Calendar`with date 2012-12-31 (Gregorian) because Monday is the first day of a week with the[ISO 8601 compatible week parameters](https://developer.android.com/reference/java/util/GregorianCalendar#iso8601_compatible_setting).
```
Calendar cal = new Calendar.Builder().setCalendarType("iso8601")
.setWeekDate(2013, 1, MONDAY).build();
```
The following code produces a Japanese`Calendar`with date 1989-01-08 (Gregorian), assuming that the default[ERA](https://developer.android.com/reference/java/util/Calendar#ERA)is*Heisei*that started on that day.
```
Calendar cal = new Calendar.Builder().setCalendarType("japanese")
.setFields(YEAR, 1, DAY_OF_YEAR, 1).build();
```

```
public Builder ()

Constructs a`Calendar.Builder`.
## Public methods
### build
Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Calendar build ()
```
Returns a`Calendar`built from the parameters set by the setter methods. The calendar type given by the[setCalendarType](https://developer.android.com/reference/java/util/Calendar.Builder#setCalendarType(java.lang.String))method or the[locale](https://developer.android.com/reference/java/util/Calendar.Builder#setLocale(java.util.Locale))is used to determine what`Calendar`to be created. If no explicit calendar type is given, the locale's default calendar is created.
If the calendar type is`"iso8601"`, the[Gregorian change date](https://developer.android.com/reference/java/util/GregorianCalendar#setGregorianChange(java.util.Date))of a[GregorianCalendar](https://developer.android.com/reference/java/util/GregorianCalendar)is set to`Date(Long.MIN_VALUE)`to be the*proleptic* Gregorian calendar. Its week definition parameters are also set to be[compatible with the ISO 8601 standard](https://developer.android.com/reference/java/util/GregorianCalendar#iso8601_compatible_setting). Note that the[getCalendarType](https://developer.android.com/reference/java/util/GregorianCalendar#getCalendarType())method of a`GregorianCalendar`created with`"iso8601"`returns`"gregory"`.
The default values are used for locale and time zone if these parameters haven't been given explicitly.
Since Android 13, if the locale contains the time zone with "tz"[Unicode extension](https://developer.android.com/reference/java/util/Locale#def_locale_extension), and time zone hasn't been given explicitly, time zone in the locale is used.
Any out of range field values are either normalized in lenient mode or detected as an invalid value in non-lenient mode.
| Returns ||
|------------------------------------------------------------------------|-------------------------------------------------------------------|
| [Calendar](https://developer.android.com/reference/java/util/Calendar) | a`Calendar`built with parameters of this`Calendar.Builder`
|
| Throws ||
|--------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [IllegalArgumentException](https://developer.android.com/reference/java/lang/IllegalArgumentException) | if the calendar type is unknown, or if any invalid field values are given in non-lenient mode, or if a week date is given for the calendar type that doesn't support week dates. |

In addition to the available calendar types returned by the[Calendar.getAvailableCalendarTypes](https://developer.android.com/reference/java/util/Calendar#getAvailableCalendarTypes())method,`"gregorian"`and`"iso8601"`as aliases of`"gregory"`can be used with this method.

```
is equivalent to the sequence of the following[set](https://developer.android.com/reference/java/util/Calendar.Builder#set(int,%20int))calls:
```
set(Calendar.YEAR, 2013)
.set(Calendar.MONTH, Calendar.DECEMBER)
