how long does a habit take to form
On average it took 66 days for the participants to start a habit. (Thatâs March 6 if you are attempting a New Yearâs resolution). Another interesting result of the study was the amount of variation. Even though 66 days was average, the number of days for habit formation varied wildly from 18 days to 254 days. So, there really isnât a magic number, just an average. There was also variation in how strong the habit became, based mostly on the type of habit.
