_C_a_l_e_n_d_a_r consults the file `calendar' in the current direc- tory and prints out lines that contain today's or tomorrow's date anywhere in the line. Most reasonable month-day dates such as `Dec. 7,' `december 7,' `12/7,' etc., are recog- nized, but not `7 December' or `7/12'. On weekends `tomor- row' extends through Monday.
When an argument is present, _c_a_l_e_n_d_a_r does its job for every user who has a file `calendar' in his login directory and sends him any positive results by _m_a_i_l(1). Normally this is done daily in the wee hours under control of _c_r_o_n(1).

Your calendar must be public information for you to get rem- inder service. _C_a_l_e_n_d_a_r'_s extended idea of `tomorrow' doesn't account for holidays.
