100000

If you're counting in hexadecimal, 20.

If you prefer, use Disney's 15-month years*: 25.6.
* Although, the "100 Years" celebration lasted 17 months, and we're supposed to wear the nametags at least through the end of Month 19...

Using Dewayne's calculation method, 30-B. (Sounds like a New York apartment number to me.)

For the rest of you: I'm 32 today.
