Although the starting point was an ideological and aesthetic expression of rationalism, this calendar also had to fulfill a coordinating and integrating function. Thus the calendric reform faced a tremendous challenge: re-creating a socio-temporal order. One of the crucial socio-temporal frameworks that guide daily behavior in Western societies is the 7-day cycle of the week. In the new calendar, the week was to be replaced by the 10-day cycle or the d¨¦cade, which turned out the greatest stumbling block for calendar-reformation. Theoretically this is explained by the social nature of time and the ¡®second nature¡¯ of time reckoning, but the unawareness of a socially established weekly rhythm in our daily behavior is hard to illustrate. Today, however, society is full of traces of so-called ¡®big data¡¯ that humans leave behind. This paper uses ¡®big data¡¯ on re-charges of electronic keys to show that even though a 10-day re-charging cycle is proposed, a 7-day re-charging cycle will surface. %K social time %K French Revolution %K the week %K calendric reform %K big data %U http://www.mdpi.com/2075-4698/3/4/399
