What Time Should Your Wedding Ceremony Start? Work Backward From Sunset

Almost every wedding timeline article opens the same way. Pick a ceremony time that feels right, then work forward.

Four in the afternoon is popular. Five is popular. Someone will tell you 4:30 is the sweet spot.

None of that is a plan. It’s a preference dressed up as advice. And it ignores the one input that decides whether you get the photos you’re paying for.

Why your sunset sets your ceremony time

Take a 4 pm ceremony in Chicago in June. Then the same 4 pm ceremony in Chicago in November. Not the same wedding.

On June 15, 2027 the sun sets at 8:26 pm. So a 4 pm ceremony leaves you four and a half hours of daylight afterward.

On November 15 the sun sets at 4:30 pm. The same 4 pm ceremony is still going when the light runs out. Your recessional happens in the dark.

That’s a gap of nearly four hours between two weddings that look identical on paper.

No sample timeline can absorb that. Sample timelines are written in clock time, and the sun doesn’t care about clock time.

Photography is also the only part of your day you can’t fix later. A late cake cutting is a shrug. A speech that runs long is a story.

But there’s no version of the evening where you get the light back.

Lighting a group of eighteen people convincingly after dark costs real money and real setup time. That’s not in your photographer’s quote.

The Knot sits at the top of search results for almost every wedding timeline query. Its own guidance says this outright.

Your ceremony start time needs to work backward from when the sun sets. Then it hands you a blank spreadsheet with no sunset in it. So here’s the missing half.

The subtraction, block by block

These are the blocks that have to happen between your ceremony starting and the sun going down. That’s if you want the couple’s portraits in good light.

The durations are not mine. Wedding photographers give these numbers when asked directly, including in The Knot’s own reporting.

Family photos: 30 minutes minimum, and about 2 minutes per family combination, per photographer Micah Chaffin. Wedding party: 30 minutes for a group of 8 to 16, per photographer Kari Bjorn. Couple’s portraits: at least 30 minutes alone, 45 to 60 if you are moving between locations. Justin McCallum adds that group photos should be given 15 to 20 minutes more than people expect. All quoted by The Knot.

Do a first look and the two biggest blocks move to the morning.

Family and wedding party photos happen before the ceremony. That leaves the portraits, the walk, and the post-ceremony scatter.

That one hour is the entire practical argument for a first look. Tradition isn’t the point. The point is whether your ceremony starts at 4:41 or 5:41.

Sunset by month, 30 US cities

Times are local clock time on the 15th of each month in 2027. We work them out for each city’s coordinates, with daylight saving applied.

Your own date can sit up to about 15 minutes either side of these. So treat them as the shape of your month, not your exact answer.

The latest your ceremony can start

Same 30 cities, peak wedding season, with the 2 hours 25 minutes already subtracted.

This is the latest you can start an outdoor ceremony. Any later and the couple’s portraits won’t finish before the sun goes down. That assumes no first look.

Doing a first look? Add an hour to every number here.

Scroll sideways for April through October.

Golden hour is not an hour

This is the part that catches people out. Golden hour is a mood, not a measurement. The word hour is doing a lot of unearned work.

The usual technical definition puts golden light between two points. The sun sitting about six degrees above the horizon, and the moment it touches it.

Run that for these 30 cities on September 15. The window comes out at 31 to 40 minutes. Not sixty.

Wikipedia’s entry on the term is blunt about it. The hour “is used figuratively; the effect has no clearly defined duration and varies according to season and latitude.”

You do get a second, softer window after the sun has gone. These same cities get another 23 to 31 minutes.

That runs from sunset to the point where light is genuinely finished. It’s a different look, flatter and cooler. Plenty of photographers prefer it.

So the honest budget is roughly 35 minutes of golden light. Then about half an hour of soft light after.

Plan 30 minutes of portraits inside that. Don’t plan an hour and assume the light will wait.

The daylight saving trap

Nobody warns couples about this. It’s the single largest one-week swing in the entire calendar.

Clocks go back on the first Sunday in November. In 2027 that’s Sunday, November 7.

A wedding on Saturday, November 6 and one on Saturday, November 13 sit one week apart. The second loses about an hour of evening light in a single step.

Planning for 2026 instead? Clocks go back on Sunday, November 1 that year. The same one-week cliff sits between Saturday, October 31 and Saturday, November 7.

Across all 30 cities the loss is between 63 and 69 minutes. One exception. Arizona doesn’t observe daylight saving, so Phoenix loses five minutes and carries on as normal.

Weighing up two Saturdays in early November? That hour is worth more than almost anything else on your comparison list. And no venue is going to raise it with you.

The spring change works the other way. Clocks go forward on the second Sunday in March. A mid-March wedding gains roughly the same hour the following weekend.

If your ceremony time is already fixed

Plenty of ceremony times aren’t negotiable. Churches run slots. Some venues have a morning wedding before yours. Some have a hard 10 pm noise curfew that pushes everything earlier.

If you can’t move the ceremony, work forward instead. Then decide what you’re giving up.

• Do the first look. It buys back a full hour. No other change buys back that much.
• Cut the family photo list. At roughly two minutes per combination, a list of 25 groupings is nearly an hour. A list of 12 is 25 minutes.
• Write the actual list before the day. Give it to someone who knows everyone to read the names out.
• Move the wedding party photos to the cocktail hour. Keep the golden window for just the two of you.
• Steal ten minutes back. Is your ceremony too late for a proper portrait block? Tell your photographer and coordinator you’ll leave the reception for ten minutes at a set time.
• Ten minutes in the right light beats an hour in the wrong light. Most photographers will suggest this trick if you ask.

What this does not account for

These are true sunset times for a flat horizon. Real venues rarely have one.

• Hills, ridges and mountains. Does your venue sit in a valley, or have high ground to the west? The sun disappears behind it well before true sunset.
• Fifteen to thirty minutes earlier is common. In a tight valley it can be more. Stand at the ceremony spot at the same time of day and watch.
• Tall buildings. Same problem in a city. It changes block by block.
• Cloud. Overcast flattens the whole thing out. It also makes the timing less critical, which is the one upside.
• Your exact date. These are the 15th of each month. Sunset moves a minute or two a day around the equinoxes. Near the solstices it barely moves at all.

Common questions

How these numbers were calculated

We work out sunset times from each city’s latitude and longitude. The math uses the NOAA solar position algorithm. It applies the standard 90.833 degree zenith, which accounts for atmospheric refraction and the sun’s apparent size.

Local clock times come from each city’s IANA time zone, so we apply daylight saving correctly. That includes Arizona, which doesn’t observe it.

Golden hour uses a solar elevation of six degrees. The end of usable light uses civil twilight, six degrees below the horizon.

Spot checks against published almanac times agree to within one minute. We checked New York, Los Angeles, Chicago, Seattle and Miami.

Photography durations come from the photographers quoted in The Knot’s reporting on formal photos. The golden hour definition follows the standard usage described here.
