Both the calendar and the development of mechanical clocks are rooted in the Church’s recognition of the need to see the world as sacred. Like the Sabbath and the feast of ancient Israel, time and seasons remind us that our lives are not ultimately our own and are instead part of the larger story of creation to redemption. In other words, as demanding as the clock can be, the Christian notion of time should help us from viewing the days of our lives in purely secular terms.

Throughout the Bible, for example in Galatians 4:4 or Paul’s speech to the “Men of Athens” recorded in Acts 17, God is described as a God of historical precision. He is outside of but fully in control of time and place. This distinctive of the Judeo-Christian understanding of God stands in sharp contrast to pagan and polytheistic notions of deities and time, and dramatically shaped human history. Today, Leap Day, is an appropriate day to think about our relationship to time.  

One of the earliest examples of time anxiety in history is found in the French song “Frère Jacques.” In it, Brother James is rebuked for sleeping and not ringing the Matins bells at midnight. The song reflects the seriousness with which the Church took the times designated for prayer. Following Psalm 119:164, which says, “Seven times a day I praise you for your righteous rules,” monastic liturgies included seven set times for prayer.  

Initially, given the changing length of day and night throughout the year, liturgical hours were not fixed. Instead, the Church regularized the hours by measuring the passage of time. By the 1200s, the mechanical clock was invented to keep pace with a chime that signaled when to ring the bells for the monastic hours.  

Not long after, mechanical clocks appeared in city towers. In 1288, the predecessor to the tower clock known as “Big Ben” went up across from Westminster Abbey. In 1292, a clock was built in Canterbury Cathedral. The oldest surviving tower clock in England, dating to 1386, is at Salisbury Cathedral. In addition to time, these clocks often marked heavenly phenomena. The most elaborate surviving example is in Prague. Installed in 1410, this clock told time using a standard 24-hour day, as well as in “Italian time,” which put the 24th hour at sunset.
