How long is the time-gap between "Tangled" and "Tangled Ever After"?

I think not very long. Perhaps only several weeks or only one month because Rapunzel's hair is still short and messy, like it was just cut by Flynn.

I think Flynn only exaggerated when he said "After years and years and years of asking and asking and asking"... in Tangled ending. I suppose he only proposed Rapunzel SO MANY times in short time and Rapunzel kept answering him "no" before finally said yes.
