The Alan Parrish question

Question

Two stereotypical british gentlemen that don't know each other engage in this unusual conversation (it's almost as if they were a setup for a puzzle):

Gentleman A - Hello sir, I'll have you know that next month, I'll turn 49.
Gentleman B - What a coincidence, next month is my birthday too, though I'll only turn 41. Maybe we share the same birthday?
Gentleman A - Well, I'm afraid this is impossible. Anyway, I must go - Good day, sir.
Gentleman B - Good day to you, and God save the Queen!

What year is it?

Answer 1

I think the year is

1841

The first gentleman is born on

February 29th

The second gentleman was born in

1800, which was not a leap year (years divisible by 100 but not divisible by 400 are not leap years).

Additionally,

The choice of century is based on the fact that Britain needed to have a Queen in the year of the conversation (see Gentleman B's last statement), in which case this is the only one that works (Queen Victoria). For example, the ruling monarchs in 1441, 1541, 1741 and 1941 are Henry VI, Henry VIII, George II and George VI, all Kings, so the conversation couldn't have happened in any of those years.
