Need Photoshop to create a huge number of images

I have a specific design which is always being used, the only thing I am editing the is text line.

For example, the text line is a date.

1950 (save as 1950.PNG) 1951 (save as 1951.png) and so on

I have to do this for about 100 years so from 1901 to 2014. So is there a quicker way to do this?
