hi, i know this sounds stupid but i know there are 30 day medallions but what if its been 4 months on a certain date than is it 30 days later or is it the exact date 1 month later that is the persons '5 months'

to explain better my friends 4 month was on the 15th of january is his 5 months the february 15th? i feel like a goof asking this and i would assume yes but just want to be sure im not a day late. thanks
