Is Tuesday a robber's favorite day?

There is no universal “favorite day” for robberies; patterns depend on the city, period, and type of offense. For example, an analysis of 53 bank robberies in Calgary from 1990–2003 found the largest share on Tuesdays (22.5%), while data from other regions show peaks on Fridays, Saturdays, or weekends. The conclusion applies only to a specific dataset.
