To provide a semimonthly tear-off calendar which attaches importance to the display of present and future days of the week and eliminates as much display of the past days of the week as possible.

This semimonthly tear-off calendar features: (1) the days of the week for one month are divided into a first semimonthly portion and a second semimonthly portion and two sheets for every month totaling 24 sheets per year constitute this calendar, (2) the days of the week equivalent to the semimonthly portion are indicated in the upper part of the whole montly calendar and the days of the week equivalent to the consecutive semimonthly portion are indicated below. (3) the calendar is updated per half of every month, and allows the days of the week equivalent to the semimonthly portion to be constantly added anew, as the calendar is staggered by half a month, and thus the consecutive days of the week without a break can be confirmed, and (4) consequently, as the calendar is clear of the indication of the past half of the month and is visually comprehensible.
