Break a date and time into component parts
Although YEAR(), MONTH(), and DAY() are helpful functions and are easy to remember, we often want to break out dates into different component parts such as the day of week, week of year, and second after the minute. This is where other functions we have learned come into play.
Here we will use the night the Berlin Wall fell, November 9th, 1989.
