When we learn English, we always find we have difficulties in remembering the names of the months. Therefore, if we know something about the history of the months, possible it won’t be very hard for us to remember them. The followed is one example. January was named by God Janus. He was a strange god because he has two faces. He could look in the two directions. He could look forward or backward at the same time. He was the god of endings and beginnings. January is the month that one looks forward to the New Year and thinks about the past year.

Now can you share us the stories about the rest of the months?
