How much time is remaining of 2x earning rate

Salad frequently does 2x earning rates over the weekend and as xp rewards during the seasons, so I think it would be useful to have something that tells us how much time we have remaining with 2x earnings. saladio
This tells us how much we have made , but doesn’t give much hint as to how much time we have left. Not sure what the out of 16 part is since I won’t earn near that much in 48 hours.
