From the X792 GMG and the "in one year Frosch will die"-thing we know that the Avatar arc was roughly 1 year after the GMG arc, which would put it somewhere around July X792.

With the way FT reassembled, I'd say we are at most two month later, so that would likely put the current date sometime around August to Octoblre X792.

But since it snows in Magnolia in winter and the weather seems to be fine and warm judging by what people are wearing, more likely August.
