The Russian folk calendar is an essential part of traditional culture. Segments or points of calendar time have long organized a person's daily life throughout the year. In the ethnolinguistic dictionary, one can find not only calendar names (names of days, weeks, holidays, eve, fasts, etc.), but also rituals, customs, signs associated with them. The collected material reflects the Russian cultural and linguistic tradition of the XIX-XX centuries. The dictionary is intended for specialists in linguistics, folklore, ethnography, as well as for everyone who is interested in the language, history and culture of the Russian people.
