DATEPART allows you to retrieve components of a date.
You can extract also YEAR, MONTH, DAY, HOUR, MINUTE, SECOND.
DATEPART(YEAR, d) DATEPART(MONTH, d) DATEPART(DAY, d) DATEPART(HOUR, d) DATEPART(MINUTE, d) DATEPART(SECOND, d)
In this example you get the year and the month from the date
SELECT whn ,DATEPART(YEAR, whn) AS yr ,DATEPART(MONTH, whn) AS mnth FROM eclipse
SELECT whn ,EXTRACT(YEAR FROM td) AS yr ,EXTRACT(MONTH FROM td) AS hr FROM eclipse
