How to remember March is the 3rd month
Think of “March” and remember that it’s the month when spring begins—and spring is the third season? Not exactly, but March is the third month. Or use the knuckle trick: March is on a knuckle (31 days), and it’s the third knuckle if you start with January on the first knuckle.
Another way: September (7 in Latin) was originally the 7th month, but after calendar reforms, March became 3rd.
