Mainly because a date, at least in PostgreSQL, is by definition a month, day, and year. You could just arbitrarily set the day to "01" because every month starts with day 1, I guess. Perhaps if you said what you want to do with this type of date field? Of course, if you really wanted to, you could create your own data type and conversions. But that still wouldn't be a "date", exactly. -- My sister opened a computer store in Hawaii. She sells C shells down by the seashore.
