Like twins, two fetuses eventually share the same womb and develop alongside each other. Both babies are usually delivered at the same time. Unlike twins, embryos from superfetation don't form during the same menstrual cycle. As a result, they're different gestational ages (in different stages of pregnancy).
When people refer to Irish twins, it's important to recognize that although the siblings are close in age, they are not actually twins. In other words, they were not born during the same gestational period. Calling them Irish twins is just an informal way of classifying siblings that are born close together.
Yes, you read that right. Twins (non-identical) can be born at completely different times, sometimes even years apart. Let me tell you more.
