In the Jackalopian calendar, Larrikin Days are traditionally the fourth Tuesday of each month. On these days, jackalopes are encouraged to express their larrikins, their “true selves”. A jackalope will have at least one larrikin name, and most jackalopes have several names for different aspects of their true selves. Some of these may be secret identities, but most are shared with family, friends or the public. A nom de guerre or nom de plume would be a larrikin name.
