About Date Difference
The interval between two calendar dates can be expressed in days, weeks, or average months. Day counts are exact; month figures use an average month length.
Important considerations
Average months (about 30.44 days) are approximations. For contracts or legal deadlines, count exact calendar days or consult the specific rules that apply.
