Killing Time on Wikipedia

To further align myself with Chandler Bing...taken directly from Wikipedia....

Chandler's birthday is most likely in early April. In the episode where a month-early surprise party for Rachel is thrown, Rachel says that Chandler's birthday is before hers. Therefore, his birthday would have had to be after or on Rachel's party day (April 8) and before Rachel's birthday (May 5). In "The One with Unagi", an episode that takes place on February 24, Monica says that Chandler's birthday is in a month and a half. A month and a half from February 24 is early April.

Yet something else we have in common...I KNEW he was an Aries!!
