Provided Methods

Extract month from underlying NaiveDateTime representation. Returns the year number in the calendar date.

Extract quarter from underlying NaiveDateTime representation. Quarters range from 1 to 4.

Extract month from underlying NaiveDateTime representation. Returns the month number starting from 1.

The return value ranges from 1 to 12.

Extract weekday from underlying NaiveDateTime representation. Returns the weekday number where monday = 0 and sunday = 6

Returns the ISO week number starting from 1. The return value ranges from 1 to 53. (The last week of year differs by years.)

Extract day from underlying NaiveDateTime representation. Returns the day of month starting from 1.

The return value ranges from 1 to 31. (The last day of month differs by months.)

Extract hour from underlying NaiveDateTime representation. Returns the hour number from 0 to 23.

Extract minute from underlying NaiveDateTime representation. Returns the minute number from 0 to 59.

Extract second from underlying NaiveDateTime representation. Returns the second number from 0 to 59.

Extract second from underlying NaiveDateTime representation. Returns the number of nanoseconds since the whole non-leap second. The range from 1,000,000,000 to 1,999,999,999 represents the leap second.

Returns the day of year starting from 1.

The return value ranges from 1 to 366. (The last day of year differs by years.)
