The first day of fall arrives on Tuesday, September 22 in the United States and Canada, at 8:05 p.m. Eastern Time. If you are reading this from the United Kingdom, Ireland, or Australia, your calendar will say Wednesday, September 23 — and that is not an error. The equinox happens at one single moment worldwide, but that moment falls on a different calendar date depending on where you stand.
That small detail is worth pausing over. The same sun, the same instant, and yet the day is named differently across the earth. It is a quiet reminder that the turning of the seasons was never ours to schedule. Scripture puts it plainly: “And he changeth the times and the seasons” (Daniel 2:21).
When Is the First Day of Fall?
The astronomical first day of fall is the autumnal equinox — the moment the sun crosses the celestial equator moving from north to south.
Autumnal equinox 2026: September 23, 00:05 UTC
| Location | Local date and time |
| New York / Toronto (EDT) | Tue, Sept 22 — 8:05 p.m. |
| Chicago (CDT) | Tue, Sept 22 — 7:05 p.m. |
| Denver (MDT) | Tue, Sept 22 — 6:05 p.m. |
| Los Angeles / Vancouver (PDT) | Tue, Sept 22 — 5:05 p.m. |
| London / Dublin (BST/IST) | Wed, Sept 23 — 1:05 a.m. |
| Sydney (AEST) | Wed, Sept 23 — 10:05 a.m. |
Why your date may say September 23
Most American websites publish the equinox date in Eastern Time and leave it there. Because the 2026 equinox lands so close to midnight UTC — just five minutes past — anyone east of the Atlantic crosses into the next calendar day before the moment arrives.
So both dates are correct. September 22 is correct for North America. September 23 is correct for Britain, Ireland, Europe, and Australia. Nobody’s calendar is wrong.

Astronomical Fall vs Meteorological Fall
There is a second reason people disagree about when autumn begins, and it has nothing to do with time zones.
| Astronomical fall | Meteorological fall | |
| Start | The September equinox (Sept 22 or 23) | September 1, every year |
| End | The December solstice | November 30 |
| Based on | Earth’s tilt and orbit | The annual temperature cycle |
| Used by | Calendars, almanacs, general public | Weather services, climate records |
Meteorologists group the year into four tidy three-month blocks so that seasonal temperature and rainfall averages can be compared cleanly from year to year. By that definition, fall began on September 1 — which is why weather reports often speak of autumn weeks before the equinox arrives.
Neither definition is more “official” than the other. They simply answer different questions.
What Actually Happens at the Equinox
The word equinox comes from the Latin aequus, meaning equal, and nox, meaning night. At the equinox, the earth’s axis is tilted neither toward nor away from the sun, and daylight and darkness fall into near-perfect balance across the globe.
After that moment, the balance tips. In the Northern Hemisphere the nights grow longer than the days, and they continue to lengthen until the winter solstice in December.
One common misunderstanding is worth clearing up: day and night are not exactly twelve hours each on the equinox. Sunrise is measured from the moment the sun’s upper edge appears, and sunset from the moment its last edge disappears — and the earth’s atmosphere bends the light so that the sun appears above the horizon slightly before it truly is. Together these add several minutes to the daylight side of the ledger. The date of true equal day and night, called the equilux, arrives a few days after the equinox.
If you are reading this from Australia or New Zealand
September brings the opposite season below the equator. The same equinox that begins autumn in the north begins spring in the Southern Hemisphere. Australian and New Zealand readers looking for the first day of autumn should look to March, when the March equinox turns the seasons the other way.
What the Bible Says About the Changing of Seasons
Here the calendar stops and something older begins. Long before anyone measured the celestial equator, Scripture spoke of seasons as an appointed order — not an accident of astronomy, but a covenant kept.
Genesis 8:22 — “While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.”
This verse comes immediately after the flood. The seasons are given as a promise: as long as the earth endures, the cycle will hold. Every equinox is that promise keeping itself.
Genesis 1:14 — “And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years.”
The sun and moon are described as timekeepers from the fourth day of creation. The equinox is not a rival system of reckoning; it is the mechanism Genesis describes, observed carefully.
Psalm 74:16-17 — “The day is thine, the night also is thine: thou hast prepared the light and the sun. Thou hast set all the borders of the earth: thou hast made summer and winter.”
Psalm 104:19 — “He appointed the moon for seasons: the sun knoweth his going down.”
Daniel 2:21 — “And he changeth the times and the seasons: he removeth kings, and setteth up kings: he giveth wisdom unto the wise, and knowledge to them that know understanding.”
Ecclesiastes 3:1 — “To every thing there is a season, and a time to every purpose under the heaven.”
Acts 14:17 — “Nevertheless he left not himself without witness, in that he did good, and gave us rain from heaven, and fruitful seasons, filling our hearts with food and gladness.”
Psalm 65:11 — “Thou crownest the year with thy goodness; and thy paths drop fatness.”
James 1:17 — “Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.”
That last verse holds the whole matter together. The light shifts; the Father of lights does not. The days shorten, the leaves let go, the year turns toward winter — and none of it touches His constancy.
Is the Autumn Equinox a Pagan Festival?
This question comes up every September, and it deserves a straight answer rather than a nervous one.
The equinox itself is an astronomical event, like sunrise or a full moon. It is not a festival, a rite, or a religious observance. It simply happens, whether or not anyone marks it.
It is also true that many ancient cultures built harvest festivals and religious ceremonies around the September equinox, and that some modern groups still observe it ceremonially. That history is real, and believers who are cautious about it are not being unreasonable.
But the distinction most Christian teachers draw is between the event and the ceremony. Noticing that the days have grown shorter, and giving thanks to God for a faithful harvest, is not participation in anyone’s ritual. Scripture itself instructed Israel to keep a harvest feast — the Feast of Tabernacles fell in this same season, and Deuteronomy 16:15 ties it directly to the gathering in of the increase.
The practical test many believers apply is simple: who is being thanked? Marking the first day of fall as a moment to give thanks to the Lord for seedtime and harvest sits comfortably within Genesis 8:22. Observing it as a ceremony directed elsewhere does not. The date is neutral; the heart is not.
Five Prayers for the First Day of Fall
1. A prayer of thanks for the turning year
Heavenly Father, You have set the sun and moon in their courses, and by them You have marked out our days. As summer ends and autumn begins, I thank You that the seasons still turn exactly as You promised they would. Teach me to receive this new season from Your hand rather than to resist it. In Jesus’ name, Amen.
"While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease." — Genesis 8:22
2. A prayer for a season of letting go
Lord, the trees release their leaves without fear, knowing that Your seasons are trustworthy. Show me what I am holding that I was never meant to keep. Loosen my grip on old worries, old grievances, and old plans that were never Yours. Let this be a season of surrender rather than striving. Amen.
"To every thing there is a season, and a time to every purpose under the heaven." — Ecclesiastes 3:1
3. A prayer for the shortening days
Father, the nights are growing longer, and darkness comes earlier now. Where the shorter days weigh on my spirit, be my light. Keep me from discouragement as the light fades, and remind me that You are the same in every season. Amen.
"Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning." — James 1:17
4. A prayer for a fruitful harvest
Lord of the harvest, You have said that in due season we shall reap if we faint not. Where I have sown in prayer, in service, and in patience, I ask You to bring the increase in Your own time. Guard me from weariness in well doing. Amen.
"And let us not be weary in well doing: for in due season we shall reap, if we faint not." — Galatians 6:9
5. A prayer for the household as autumn begins
Gracious God, bless this home as the season changes. Keep each one under this roof in health and in peace. As schedules fill and the evenings draw in, make our house a place of rest and of thanksgiving. Crown this year with Your goodness. Amen.
"Thou crownest the year with thy goodness; and thy paths drop fatness." — Psalm 65:11
The Harvest Moon and Harvest Services
The full moon falling nearest the September equinox carries an old name: the Harvest Moon. Around the equinox, that full moon rises close to sunset for several evenings in a row, which once gave farmers extra light to bring in the crop after dark. The name is agricultural, not ceremonial.
In many churches the equinox quietly opens the harvest season. Congregations across the United Kingdom hold Harvest Festival services in late September and early October, and American and Canadian churches often mark a harvest Sunday before Thanksgiving. If your church keeps a harvest service, the first day of fall is a natural moment to begin praying toward it.
Simple Ways to Mark the First Day of Fall
- Read Genesis 8:22 aloud at breakfast. One verse, spoken at the start of the day, sets the tone for a whole season.
- Step outside at sunset. Notice how much earlier the light goes than it did in July. Let the observation become thanksgiving rather than complaint.
- Write down one thing you are releasing. The trees model it; the paper makes it real.
- Name the harvest. List three things God brought to fruit this year that you did not make happen yourself.
- Pray over the coming season. Autumn carries full calendars — school terms, church programmes, holidays. Pray over it before it arrives rather than after it overwhelms.
Frequently Asked Questions
Is the first day of fall always September 22?
No. The astronomical first day of fall falls on September 22 or 23 depending on the year and your time zone, because the earth’s orbit does not divide evenly into calendar days.
Why do some sources say fall starts September 1?
That is meteorological fall, used by weather services so that seasonal climate data can be compared consistently. Astronomical fall begins at the equinox.
Are day and night exactly equal on the equinox?
Almost, but not precisely. Daylight runs a few minutes longer because of how sunrise and sunset are defined and because the atmosphere bends sunlight above the horizon.
When is the first day of fall in Australia?
In the Southern Hemisphere, autumn begins at the March equinox. The September equinox begins spring there.
Does the Bible mention the autumn equinox?
Not by that name. Scripture describes the sun and moon as given “for signs, and for seasons” (Genesis 1:14) and promises that seedtime and harvest will not cease (Genesis 8:22), but it does not name the equinox as an observance.
What is the Harvest Moon?
It is the full moon nearest the September equinox. Around that time the moon rises close to sunset on successive evenings, historically extending working light for the harvest.
