Why do BS and AD ages differ?

Because BS and AD months have different lengths and the year start dates differ (BS year begins in mid-April AD). The year count is the same, but the months and days break down differently.

How is the next birthday calculated?

From your BS birth month and day — matching the Nepali custom of celebrating birthdays on the BS date. The AD equivalent of that date is also shown.
