Can twins be different ages

Theoretically, yes. Twins are usually born at least a few minutes apart, sometimes an hour or two apart. It is rarely possible for delivery of twins to be spaced out even more than that. If a woman delivered one twin shortly before midnight and the another twin shortly after midnight, then the two twins would be born in different days and actually have different birthdays--so they would be 1 day apart in age.

Twins are different ages in every case. However, the question is by what time difference. In other Words, one minute, two minutes, ten minutes. Still, you will not find them separated by much more in most cases. Twins develop within the the same pregnancy.
