Use your device's location, or enter coordinates manually, to see today's sun times — calculated entirely on your device.
Sunrise and sunset times depend entirely on latitude, longitude, and date — there's no way to calculate them without knowing where you are, or without you entering coordinates manually.
No, your coordinates are used locally in your browser to run the calculation and are never transmitted anywhere.
Small differences (usually under a minute) can occur depending on how atmospheric refraction and elevation are accounted for — this is normal and expected between different calculators.
Yes, use the date field to check sunrise and sunset for any past or future date at the given location.
