public CalendarConstraints build()

Builds the CalendarConstraints object using the set parameters or defaults.

public CalendarConstraints.Builder setEnd(long month)

A UTC timeInMilliseconds contained within the latest month the calendar will page to. Defaults December, 2100.

If you have access to java.time in Java 8, you can obtain a long using java.time.ZonedDateTime.

LocalDateTime local = LocalDateTime.of(year, month, 1, 0, 0);
local.atZone(ZoneId.ofOffset("UTC", ZoneOffset.UTC)).toInstant().toEpochMilli();

If you don't have access to java.time in Java 8, you can obtain this value using a java.util.Calendar instance from the UTC timezone.

Calendar c = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
c.set(year, month, 1);
c.getTimeInMillis();

public CalendarConstraints.Builder setFirstDayOfWeek(int firstDayOfWeek)

Sets what the first day of the week is; e.g., Calendar.SUNDAY in the U.S., Calendar.MONDAY in France.

public CalendarConstraints.Builder setOpenAt(long month)

A UTC timeInMilliseconds contained within the month the calendar should openAt. Defaults to the month containing today if within bounds; otherwise, defaults to the starting month.

If you have access to java.time in Java 8, you can obtain a long using java.time.ZonedDateTime.

LocalDateTime local = LocalDateTime.of(year, month, 1, 0, 0);
local.atZone(ZoneId.ofOffset("UTC", ZoneOffset.UTC)).toInstant().toEpochMilli();

If you don't have access to java.time in Java 8, you can obtain this value using a java.util.Calendar instance from the UTC timezone.

Calendar c = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
c.set(year, month, 1);
c.getTimeInMillis();

public CalendarConstraints.Builder setStart(long month)

A UTC timeInMilliseconds contained within the earliest month the calendar will page to. Defaults January, 1900.

If you have access to java.time in Java 8, you can obtain a long using java.time.ZonedDateTime.

LocalDateTime local = LocalDateTime.of(year, month, 1, 0, 0);
local.atZone(ZoneId.ofOffset("UTC", ZoneOffset.UTC)).toInstant().toEpochMilli();

If you don't have access to java.time in Java 8, you can obtain this value using a java.util.Calendar instance from the UTC timezone.

Calendar c = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
c.set(year, month, 1);
c.getTimeInMillis();

public CalendarConstraints.Builder setValidator(CalendarConstraints.DateValidator validator)

Limits valid dates to those for which isValid is true. Defaults to all dates as valid.
