Loose-leaf, desk calendar refill helps keep you on top of each day's events and appointments. Dated refill is sized and two-hole punched to fit standard 17-style bases (E17, M17, and J17). Each weekday on a two-page spread includes ruled, half-hourly appointment times from 7 AM to 5 PM as well as count of days/days remaining, holidays, and past, current and future months reference. Planning pages range 12 months from January to December. Bases and refills are sold separately.
