FirstDayOfMonth(date)
Any date.
Years from 0 to 29 are interpreted as 21st century values. Years 30 to 99 are interpreted as 20th century values.
When passing a date/time value as a string, make sure it is enclosed in quotes. Otherwise, it is interpreted as a number representation of a date/time object, returning undesired results.
