How long is the January river? You may think that you have never heard of the January river but you almost certainly have heard of the city known by its three letter name. Portuguese and Spanish for river is rio and you almost certainly have heard of Rio de Janeiro.

It was January of 2021 when I wondered how long the January river is and found out that it doesn’t exist. In January 1502 it was named because there was expected to be a river that never was.
