A useful calculation question identifies the exact result you are checking. The details below help distinguish a location, time-zone or definition difference from a problem in the calculation.
Prepare a calculation report
– The page where you found the result and the event name, such as sunrise, civil dusk or evening golden hour. – The selected place and coordinates, if available. – The calendar date and displayed time zone. – The time shown by this site and the value you expected. – A link to the comparison source, including its definition or elevation setting if available.
A screenshot can help show the selected inputs, but a time without its date and location is not enough to reproduce the result. Avoid including private account details or other information unrelated to the calculation.
Check common differences first
An exact one-hour difference often points to a time-zone or daylight-saving convention. A difference of a few minutes may come from coordinates, rounding, model assumptions or a local horizon. Golden-hour and blue-hour windows can differ because services use different altitude ranges.
For an observation, note whether the horizon was open or blocked by terrain or structures. The calculator uses a standard horizon, so the moment the Sun appears above a ridge is not the same event as sunrise over a level horizon.
Describe a website problem
If a control does not work, note the browser, device and action you took. Say whether the problem affects place search, location permission, the map, weather or solar results. Those features use different parts of the site, so the distinction helps identify the issue.
You can also check the methodology and sources for the definitions and services involved.
Frequently asked questions
Should I report a blank weather card as a sunrise error?
Describe it as a weather-loading problem if the solar times still appear. Weather is supplied separately and can be unavailable while the astronomical calculation continues to work.
Do I need to share my home address?
No. A public location or approximate coordinate that reproduces the issue is usually more useful than a personal street address. Include only the information needed to describe the calculation.
What if another site shows a different golden hour?
Check both sites’ altitude definitions first. This site uses −4° to +6° for golden hour. A different chosen band can produce a different interval without either service making an arithmetic error.
