Expected identifier, got '1' error?

1: game.service("Lighting")
while true do
	wait(0.1)
	1:SetMinutesAfterMidnight(1:GetMinutesAfterMidnight() +1) 
end

I keep getting the error, Expected identifier, got '1' The error seems to be on line 1.

You cannot have numbers as variables. Try using one, not 1.
