The Old Farmer's Almanac's Best Days for 2021 by Activity! Find out when to start a diet to lose weight, cut hair to increase growth, plant vegetables, quit smoking, lose weight, wean, mow grass to slow growth, and more activities, based on the Moon’s sign. 

To determine the Best Days, we look at several factors, including the position of the Moon in the 12 signs of the Zodiac, as well as the lunar phase. Planetary relationships may also be considered. When positions and/or phases are suitable, tradition says that activities are more likely to yield favorable results.
