Elephants are mammals, and the largest land animals alive today. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kg (265 lb). An elephant may live as long as 70 years, sometimes longer

Reproduction
Females (cows) reach sexual maturity at around 9-12 years of age and become pregnant for the first time, on average, around age 13. They can reproduce until ages 55-60. Females give birth at intervals of about every 5 years. An elephant's gestation (pregnancy) period lasts about 22 months (630-660 days), the longest gestation period of any mammal, after which one calf typically is born. Twins are rare. Labor ranges in length from 5 minutes to 60 hours. The average length of labor is 11 hours. At birth, calves weigh around 90–115 kg (200–250 lb), and they gain 1 kg (2–2.5 lb) a day. In the wild, the mother is accompanied by other adult females (aunts) that protect the young, and baby elephants are raised and nurtured by the whole family group, practically from the moment they are born.

The answers you have received that say about 22 months are correct. However, the reason is not just because they are so large. The Grey Whale calf is much bigger at birth but the gestation is only 12 months. The answer to your question “Why?” is that there is no answer yet. There are many complicated factors, size being just one of them.
Also the statement that elephants give birth when over 50 years old is incorrect. The oldest on record is 41. Elephants can live into their 70s, just like humans can live to be 115 years old. But how many people live that long? Very, very few. It is the same with an elephant. A 55-year-old elephant is a very old animal. The average in zoos is 44. In circuses it is a little higher and in the wild it is a little lower. (A circus elephant holds the record.)

Why is because of their large size, because the larger the mammal the longer they carry the fetus

By law any insurance that you have must cover the baby for the first 30 days but you are required to contact the insurance office and bring necessary information like a copy of birth certificate or something that validate the birth of your baby. You should then apply for social security card right away and then send them a copy of the card or the letter that validates that you have applied with the number and that it will be mailed to you in 2 weeks. Stay on top of it because sometimes they give people a hard time about what they will accept and won't accept. Good luck!

it's close to 2 yrs, because they r so big of course
think about it , a dog or cat takes about 3 months and humans take 9 months so the bigger the animal the longer it takes

22 months; because that is how long it takes for the fetus to develop to the point that it can survive outside the uterus.
