Jamie Carter observes how dependent religious events such as Easter are on the moon. Humans celebrate these events not because of a numbered calendar date, but because of lunar cycles.

When is Easter? That’s easy—Easter is on Sunday, April 12, 2020 for western christians and on Sunday, April 19, 2020 for eastern orthodox christians.

Two dates, forever changing—Easter does not have a specific date.

Unlike Christmas Day, it changes every year depending on something that most people don’t often associate with the christian religion—the moon.

For the world’s 1.8 billion muslims, the exact date of Ramadan is determined by the lunar cycle—with the physical sighting of the crescent moon the day after a New Moon the critical factor. In 2020, that’s Thursday, 23 April—the evening after the next New Moon—unless the crescent isn’t sighted, in which case it will begin the evening after when the New Moon is higher in the post-sunset sky…

Easter is celebrated by roman catholics and protestant christians on the first Sunday after the first full moon occurring on or after the vernal equinox as determined by the Gregorian calendar. That’s the rule. Since the equinox occurred on March 20, 2020 and the “Super Pink Moon” appeared on April 7, 2020, so the date of Easter Sunday was automatically set for Sunday, April 12, 2020. It’s been that way since the year 325 A.D…

Although its 99% a lunar festival in terms of the date it’s held, Easter isn’t just determined by the moon’s phases. The ecclesiastical authorities fix the vernal equinox at March 21, thereby limiting the dates when Easter can occur…

Clocks are a modern invention, as is the convention of global calendars standard time. “Prior to the Gregorian calendar, which is our standard calendar now, calendars were set by the phases of the moon because we didn’t have clocks,” said Dr. Jackie Faherty, Senior Scientist and Senior Education Manager jointly in the Department of Astrophysics and the Department of Education at the American Museum of Natural History.

The Gregorian calendar is a solar calendar that evolved from a lunar calendar. “Standards of time only began when people wanted to set train timetables, and this idea that we have a universal time that we can all get from looking at our watch is something we take for granted,” said Faherty…

Much of our calendar comes from astronomy,” said Faherty, stating that Monday is named after the Moon. “It’s a constant and observable feature that you can get your own understanding of, with its changing phases a great way of tracking the seasons.”

Our concepts of time, and the language we use to talk about it, owe a lot to the Moon and the Sun.“There’s so much to our keeping track of our time that’s related to astronomy, and so much in the early days was set and understood by the Moon—so that was the way that many religious calendars were calculated, and still are today,” said Faherty.

David Miller interviews Pagan teacher and author Waverly Fitzgerald, who says that natural time in her book is a reference to a time that can be touched. Conversely, artificial time is characterised as a temporality that is abstracted into homogenous, identical parts. Fitzgerald notes that the rhythms of natural time intersect with Pagan spirituality.

[Miller] You make a distinction in your book between what you call “natural time” and “artificial time.” Isn’t time really an abstraction? So how can it be natural?

  • [Fitzgerald] That was my quest (in writing the book), to answer that question. What is natural about time? And the answer had to do with looking at different time intervals and noticing that some of them you can actually see, touch and smell. You can tell when it’s day and when it’s night. You can observe the moon in the sky and after a few days of observing it you can know whether it’s waxing or waning. You can know what season it is by walking outside. These are all, for me, examples of natural time. What I noticed about all of those cycles was that they were, in fact, cycles. They had, if you will, an “on” and “off” position, or a maximum and a minimum. And then they had a slow gradual progression to and from that state. That’s really different than when you look at a calendar, a schedule or a clock, where everything is completely regular and all times are presumed to be exactly the same. There are blank spaces on the calendar, and you can put the same amount of activity into each of them. There is this sort of unnatural — that’s why I call it artificial — aspect to them, which I think gets us in a lot of trouble because we think, “Oh, we can do this thing in this amount of time,” when really all of these other factors play into it that are not under our control.

You’re not suggesting we throw out our calendars and clocks, are you?

  • No. There are really good reasons why those tools were developed to synchronize activities. But I think as biological beings we also need to be aware of our natural rhythms, including the need for rest. I think many people believe that when you sit down at your desk you should be working flat out at the top of your productivity for the maximum amount of time. At least that’s the ideal. But there something called the ultradian rhythm, a biological cycle where there is an arousal period, a period of waking up and becoming alert, and then a period of getting restless or bored or unfocused and then a time of rest. If you start to observe that cycle in your life, it allows you to have a more relaxed and effective approach to your daily tasks…

How and why do religion or spirituality and slow time intersect, do you think?

  • Most of the major religions have a seasonal liturgy, even though it may be sort of buried. If you look at Christianity, with the Easter cycle and the Christmas birth, there is this lovely use of the seasons to tell a story, and the same is true in the Jewish religion. And, of course, the pagan religion really works with this notion of the seasons and the cycle. So there is a very deep connection between this notion of cyclical time and spirituality. And there is a message of hope that things will come around again, that we may feel despair but spring will come again. It is a pretty profound metaphor that is imbedded in our lives (Miller 2008).
