Free sunrise sunset calculator: get exact sunrise and sunset times for any latitude and date, with a worked Lahore example and honest limits.
A sunrise sunset calculator tells you the exact time the sun rises and sets for any place on any day. Enter a latitude and a date, and it returns the two times that frame your daylight — no almanac, no manual maths, no guessing from yesterday's times.
That matters more than most people expect. Photographers plan golden-hour shoots around it. Farmers time fieldwork. Travellers pick the right hour for a hike. Solar installers estimate usable daylight. And anyone planning an outdoor event needs to know when the light runs out. This guide walks through the free sunrise sunset calculator on CodexFuse, with a full worked example, honest limits, and the fastest way to use the result.
What Is a Sunrise Sunset Calculator?
A sunrise sunset calculator is a free online tool that computes the time of sunrise and sunset for a chosen location and date. It works from your latitude and the day of the year, because those two inputs decide how long the sun stays above the horizon.
How to Use the Sunrise Sunset Calculator on CodexFuse
The tool keeps the workflow deliberately short — no settings panels, no extra fields to decode.
- Enter the latitude. Type the latitude of the place you care about — for example, 31.52 for Lahore or 51.50 for London. Latitude is the number that decides how long the day is.
- Enter the day. Pick the date you want times for. Sunrise and sunset shift a little every single day, so always calculate for the actual date, not a nearby one.
- Calculate the times. Hit calculate and the tool returns the sunrise time and the sunset time for that latitude and day.
- Copy the result. Use the built-in copy option to paste the times into a shoot plan, a calendar invite, or a message to your team.
One thing to know before you start: the tool asks you to log in or create a free account before you can use it. That takes a minute, and once you are in, the calculator itself is free and unlimited.
Always calculate for the exact date of your plan, not for today. Around the solstices the shift is small, but near the equinoxes sunrise moves by roughly two minutes a day — enough to miss the light you planned for.
A Worked Example: Planning a Golden-Hour Shoot in Lahore
Here is a complete run-through with real inputs, so you can see exactly what the tool gives you and how to use it.
The scenario: Ayesha, a freelance photographer in Lahore, has a client who wants outdoor portraits at golden hour on 15 December 2026 — roughly the hour after sunrise and the hour before sunset. She needs both times before confirming a call time.
The inputs she enters:
- Latitude: 31.52 (Lahore)
- Day: 15 December 2026
The outputs the tool returns:
- Sunrise: around 6:52 AM
- Sunset: around 5:08 PM
How she uses them: Ayesha now knows her daylight window is about 10 hours and 16 minutes. She books the morning session for 7:00–8:00 AM and the evening session for 4:00–5:00 PM, catching both golden hours. She messages the client both call times, copies the figures into her shoot notes, and sets an alarm for 6:15 AM. The whole calculation took under a minute — and it removed the one variable that could have ruined the shoot.
Notice what the tool did not do: it did not pick the location for her, it did not check the weather, and it did not decide which hour was best. It answered one precise question — when does the sun rise and set — and left the creative decisions to her.
Missed daylight means missed shoots, wasted trips, and plans that fall apart at dusk. Run your times through the free sunrise sunset calculator, then keep every tool you rely on — hosting, email, security, backups — in one fully managed place on CodexFuse credits.
Get Started with CodexFuseWhy Do Sunrise and Sunset Times Change?
Two things move the times: where you are and when it is. Latitude decides how extreme the change is, and the season decides which direction it moves. The table below shows the same city — Lahore, latitude 31.52 — across the year.
| Date | Sunrise (approx.) | Sunset (approx.) | Daylight |
|---|---|---|---|
| 21 June 2026 | 5:00 AM | 7:20 PM | ~14 hrs 20 min |
| 21 September 2026 | 5:50 AM | 6:05 PM | ~12 hrs 15 min |
| 15 December 2026 | 6:52 AM | 5:08 PM | ~10 hrs 16 min |
| 21 March 2027 | 6:00 AM | 6:20 PM | ~12 hrs 20 min |
That is a swing of more than four hours between summer and winter in the same city — and it is wider the further you move from the equator. In London, the same four dates span roughly 8 hours of daylight in December to nearly 17 in June. This is why a calculator beats a rule of thumb: the numbers are specific to your place and your date.
Daylight saving time can shift the clock reading by an hour even though the sun itself has not moved. If your location observes DST, double-check whether the time you need is in local clock time or standard time before you lock a plan around it.
Who Actually Needs Sunrise and Sunset Times?
The tool looks simple, but the people who rely on it are not a niche. Daylight timing touches far more work than most teams realise.
- Photographers and videographers: golden hour and blue hour are short windows, and a shoot scheduled even 20 minutes late can lose the light entirely.
- Farmers and gardeners: planting, spraying, and harvesting all depend on daylight hours and on knowing when dew and frost are likely.
- Travellers and hikers: knowing sunset is the difference between a relaxed walk back and a rushed one in the dark.
- Solar installers: daylight length is the first input in any honest estimate of what a panel setup can produce.
- Event planners: outdoor weddings, markets, and sports fixtures all need a firm answer to "when does it get dark?"
- Religious observance: fasting and prayer schedules are tied to sunrise and sunset, which is why many people pair this with a dedicated prayer times tool for the full daily schedule.
If your work touches any of these, the calculator earns its place in your bookmarks. It answers in seconds a question that otherwise takes a search and a table lookup.
What the Sunrise Sunset Calculator Does Not Do
Honest limits matter more than features. Here is what this tool will not give you, and what to use instead.
- No terrain or horizon adjustment: the times assume a flat horizon. In a valley or behind a mountain, the sun disappears before the calculated sunset.
- No weather forecast: the calculator tells you when the sun sets, not whether clouds will hide it. Pair it with a weather check before any outdoor plan.
- No twilight times: civil, nautical, and astronomical twilight — the fading light after sunset — are not part of the output. Use a dedicated astronomy tool if you need those.
- Only latitude and day as inputs: make sure your latitude is right. A wrong latitude by even a few degrees shifts the times noticeably, especially in winter.
- Login required: you need a free CodexFuse account to use it. For a one-off check, a search engine's built-in sunrise answer works — but you lose the copy workflow and the rest of the toolset.

Frequently Asked Questions
Is the sunrise sunset calculator free?
Yes. The calculator is free and unlimited once you have a free CodexFuse account. There is no per-calculation charge and no daily limit on how many dates you check.
What information do I need to use it?
Two things: the latitude of the place and the day you want times for. If you do not know the latitude, search for your city followed by "latitude" — for example, "Lahore latitude" returns 31.52.
How accurate are the sunrise and sunset times?
For a flat horizon they are accurate to within a minute or two for most locations. Hills, buildings, and mountains can make the visible sunset earlier, and local weather affects whether you actually see the sun at that time.
Does it account for daylight saving time?
Check the result against your local clock when DST is in effect. The astronomical event does not move, but the clock reading does — so confirm whether the time shown matches your local time on that date.
Can I use it for any place in the world?
Yes. Any latitude works, from the equator to the polar regions. Near the poles in mid-summer or mid-winter the tool may return no sunrise or no sunset at all — that is correct, because the sun genuinely does not rise or set on those days.
How is this different from just searching "sunset today"?
A search gives you one place and one day — usually your current location, today. The calculator lets you pick any latitude and any future date, copy the result, and plan ahead. For a shoot, a trip, or a project weeks away, that forward planning is the whole point. You can also convert the result with the military time converter if your team works in 24-hour time, or work backwards from a deadline with the subtract days from date tool.
