The average menstrual cycle length -- that would be from the first day of your period until the next period begins -- is said to be 28 days. There's a misconception that anything shorter or longer than 28 days is not normal, but this isn't true. A cycle as short as 21 days or as long as 35 days is considered normal.
Columbo's first name is never explicitly revealed in the series. However, when Columbo flashes his badge in the episode Dead Weight (Season 1 Episode 3), the name 'Frank' can clearly be seen on his ID. In the german DUB befriended police detectives occasionally call him Frank. The answer is no.
Author: It was hard to tell under the dents and the paint job (or lack thereof), but the beaten, sputtering car Columbo drove en route to solving cases was a Peugeot 403 two-door convertible. Reports differ on whether it was a 1959 or 1960 model, but most agree there was little difference between the two. Though the Peugeot 403 was mass-produced by the French carmaker, the two-door convertible model was, in fact, somewhat rare. Columbo, played by Peter Falk, brags about that fact in the Season 5 episode Identity Crisis, saying there are only three of them in the entire United States.
