Calendar days vs. business days: Calendar days include all days (weekends and holidays). Business days count only Monday through Friday, excluding weekends. Our calculator shows both counts for your convenience.
Common durations: 30 days ≈ 1 month, 90 days ≈ 3 months (1 quarter), 180 days ≈ 6 months, 365 days = 1 year. These are approximations — actual month lengths vary.
All calculations are based on the Gregorian calendar and your device's local date. Business days count excludes weekends (Saturday & Sunday) but does not account for public holidays.
