Did the Middle Ages used calendars or not?

Answer 1

If you mean "Did calendars exist in the Middle Ages?", the answer is yes, but very few people had access to them or could read them. Calendars (kalendae) were part of Church liturgy, to keep track of the dates of Holy Days and the feast days of the Saints.

In the late medieval period some nobles and noblewomen kept "books of hours", which were again religious books that included a calendar of important Church dates. The average working man, even at craftsman or tradesman level would never see such a book - and could not read it if he did.

Calendars were written in Latin, with various numbers alongside the date of each month, representing complex calculations for keeping track of the Church calendar as well as the monthly calendar. They often included an astrological sign for each month and a "labour of the month" - the type of work you might expect to see going on in the fields.

Answer 2

Yes, the Middle Ages used calendars. Various types of calendars were used during this period, including the Julian calendar, which was widely used in Western Europe until the late Middle Ages, and the liturgical calendar, which was used by the Christian Church to determine religious feasts and observances. Additionally, regional calendars with local variations also existed.
