Both adjectives refer to biological or physiological cycles, ultradian meaning "recurring with a period shorter than a day," and circadian "recurring with a period of approximately 24 hours." Both adjectives have similar formations: the Latin prefix ultra- meaning "beyond, on the far side of" and circa meaning "around, about." The element -dian is formed from the Latin noun diēs "day" and the English adjective suffix -an, from Latin -ānus.
