Answer

$132,860$ ways

Work Step by Step

The birthday of the first person can be any day from the $365$ days. Since the birthdays should be different, the second person's birthday can only be a day from the remaining $364$ days (Birthday of first person is excluded from the options that second person can have). Using multiplication principle, we have Number of ways = $365\times364 = 132,860$.
