As we well know, there's a national day for just about everything. But did you know that some days are scientifically designated the most opportune moment to do thing?

For example: if you want to color your hair this month, tomorrow is the last best day to do it. You might think "Well, yeah, tomorrow is the last day of the month." But this is actually according to the 2018 Farmer's Almanac.

There is an entire chart indicating the best days of the month to do things, based on the moon signs. (If you want to color your hair in September, the best days to do it are the 1st, 27th and 28th).

It includes tasks like starting a diet, baking, traveling for pleasure and even buying a house. I'm not typically superstitious, so this just makes me laugh, but I might have to test out one of these theories and see if it goes better than normal!
