How old will he be? vs How old is he?

I met Tom today.

  1. How old will he be?
  2. How old is he?
    Is there any difference in meaning between #1 and #2?

#2 is talking about the present, while #1 is normally talking about the future. Normally #1 requires a specific date to have been mentioned. For example. “It’s Tom’s birthday next week” / “Yeah? How old will he be?”

Well, thanks! Got it.
