Looking for a perpetual calender?

When i was a teen, many years ago, I used to have a piece of paper that when i followed the rows and columns, I could tell the specific day for any date thru a 200 or 300 year period of time. So if i new a birthdate, i could find the day, for example. Now there is nothing to b found on the web, either in print or software to be located. Would like to find that old paper
