Useful to know
Does this send my location anywhere?
The calculator makes no request containing your coordinates. Your browser handles the location permission and supplies a position, which is rounded and used in temporary page state. Only your chosen date is saved locally.
Which time zone is used?
Europe/London: GMT in winter and BST in summer. The times stay in UK local time even if your device is set to another time zone.
How are the times calculated?
SunCalc calculates them locally from the date and coordinates. Terrain, buildings and weather can make usable light differ from these estimates.
