Individually, the best day to work from home will depend on a person’s schedule. That said, three particular days often get mentioned when this topic comes up: Monday, Friday, and Wednesday.
Monday is good in case you want to ease into the workweek. On the other hand, Friday works if you want to rest after a hard week at the office. A remote Wednesday is helpful for those wanting to break up the week and make it less daunting.
Work-from-home statistics don’t have any set answer to this question. However, people most often seem to consider Wednesday the best.
