Gestation is the period of time between fertilization and birth of mammals—in other words, the time spent in the mother's uterus. The shortest known gestation period is 12 to 13 days. This record is shared by three marsupials (mammals in which the young are born prematurely and finish developing in a pouch located near the mother's abdomen): the American or Virginian opossum (Didelphis marsupialis); the rare water opossum, or yapok (Chironectes minimus), of central and northern South America; and the eastern native cat (Dasyurus viverrinus) of Australia.
The longest gestation period for a mammal is that of the African elephant (Loxodonta africana) with an average of 660 days, and a maximum of 760 days.

An elephant's gestation period lasts about 22 months (630-660 days), the longest gestation period of any mammal, after which one calf typically is born

Elephants are preggers for 24 months. (2 years.)
I just found this: Read below.....
Reproduction
Cow elephants commonly mate by their 15th or 16th year, usually with a bull
that is able to contend with other bulls in the herd. A mating pair often separates
from the herd for several weeks. After a gestational period of 21 to 22 months, the
cow gives birth, usually to one calf. The calf is able to follow the herd within a
few days. Calves are vulnerable to leopards and tigers, which are among the few
nonhuman predators of elephants. The calves suckle the female's teats, which are just
behind the forelegs, for nearly five years before weaning. Cows give birth to 5 to 12
calves in a lifetime
