JDK 16
A new formatter pattern, letter 'B', and its supporting method have been added to `java.time.format.DateTimeFormatter/DateTimeFormatterBuilder` classes. The pattern and method translate `day periods` defined in Unicode Consortium's CLDR (https://unicode.org/reports/tr35/tr35-dates.html#dayPeriods). Applications can now express periods in a day, such as "in the morning" or "at night", not just am/pm. The following example demonstrates translating the day periods:
This example produces day period text depending on the time of the day and locale.
