R6 is 2000-2030 if that’s what you’re looking for; I think it’s the only world that would go past the current year. I don’t know if they’ll be updating the dates for the current ones or not.

I use Postman to quickly lease a bunch of aircraft. I just change the ID and send off the post request. It's way faster than the UI which is so slow. Click on lease->wait...click on the number of years....wait->click confirm->get sent to the aircraft info page, then you have to go back.
