"How did Anglo-Saxons tell the time?
The Anglo-Saxons used a variety of methods to tell the time, including:
Sundials: Used for general timekeeping, especially in larger homes and churches.

Church Bells: Rang to mark the hours of worship and other important events.

Calendars and Chronicles: Used to record significant events and the passage of time.

Monastic Computus: A model of time that was visible, durable, portable, and objectifiable, used by monks for religious observances.


These methods were deeply embedded in the culture and identity of the Anglo-Saxons, reflecting their understanding of time as a fundamental aspect of their daily lives and religious practices."
