Look up real sunrise and sunset times
Ask for sunrise or sunset anywhere and Zeplik reads the real solar times from the sunrise-sunset service, then answers with the actual sunrise, sunset, solar noon, day length, and twilight for the place and date. These depend on latitude, longitude, and the date through a solar calculation a language model cannot perform, so a time it names can be off by an hour or more, especially at high latitude near the solstices. This computes the real times and, when a place cannot be found, says so instead of guessing.
The lookup is free; you pay only the normal cost of the answer, shown before you send.
How it works
Name the place and date
Ask in plain language, like 'what time is sunset in Oslo today?' or add a date. The place is enough, and today is assumed if you give no date.
Zeplik computes the solar times
It resolves the place to a latitude and longitude and reads the real solar times for the date, not the model's memory, and treats each field as source data.
Read the real times
The answer states the sunrise, sunset, solar noon, day length, and twilight, all computed for the place and date rather than guessed.
Worked examples
Real prompts you can open in the composer with the text ready to review. Nothing sends on its own. Swap in your own details.
Prompt: What time is sunset in Oslo today?
Zeplik resolves Oslo and returns the real computed sunset time, rather than a time the model guessed that could be off by an hour.
Open this in ZeplikPrompt: How long is daylight in Sydney on December 21?
It computes the day length for the date from the solar times, so the answer is a real calculation rather than a recollection.
Open this in ZeplikPrompt: When does the sun rise in San Francisco tomorrow?
Given tomorrow's date it returns the real sunrise for that day, so the time comes from the computation rather than memory.
Open this in ZeplikWhat it can and cannot do
The lookup is precise about what it can verify and honest about its edges. Here is the plain posture.
Zeplik computes the solar times for the place and date, so sunrise and sunset are a real astronomical calculation, not a guess.
Every lookup carries the day length, solar noon, and civil twilight, so a golden-hour or daylight answer is grounded in the computation.
It resolves a place name to coordinates and computes the times for today, tomorrow, or a specific date you name.
If the place cannot be found, Zeplik says so rather than guessing a sunrise or sunset to fill the answer.
It returns sunrise, sunset, and twilight, from which the golden-hour window follows, but not a per-minute exposure plan for a shoot.
The service returns times in UTC. Zeplik converts using the place's timezone, but a bare coordinate with no zone is reported in UTC.
Grounded, and honest by default
- It cites the computed times. Every answer states the sunrise, sunset, and day length computed for the place and date, so nothing is vague or approximated from memory.
- It will not guess a solar time. A language model cannot do the solar calculation, so when a place is unknown Zeplik says so rather than manufacturing a plausible sunrise or sunset.
- Solar data cannot hijack the answer. The reading is treated as untrusted content: Zeplik reads and reports it but never obeys instructions embedded inside it.
Frequently asked questions
- Where do the sunrise and sunset times come from?
- From the sunrise-sunset service, with the place resolved to coordinates first, both read live and keyless. The times Zeplik returns are a real solar computation for the place and date.
- Why not just ask a chatbot when the sun sets?
- Because sunrise and sunset depend on a solar calculation a language model cannot perform, so a time it names can be off by an hour, especially at high latitude. This tool computes the real times instead.
- Can I ask for a specific date?
- Yes. Give a date like December 21, or say today or tomorrow. The times are computed for that date at the place you name.
- What timezone are the times in?
- The service computes them in UTC. Zeplik converts to the location's local time using its timezone before stating a clock time, so you get the local sunrise and sunset.
- Does a sunrise lookup cost credits?
- The lookup itself is free. You pay only the normal model-token cost of the answer Zeplik writes around it, shown before you send, exactly like any other message.
