Flat horizon, sea level
These times are computed for a level, unobstructed horizon at sea level, with an average atmosphere. Hills, mountains and buildings all bring sunset forward and push sunrise back — in steep country by half an hour or more. Refraction varies with temperature and pressure, which is worth another minute either way. Do not plan anything where being wrong is dangerous around these times. Give yourself real margin before dark.

“First light” and “last light” are civil twilight — the Sun 6° below the horizon, when there is enough light to see without a torch. A dash means the event does not happen on that date: the Moon rises about 50 minutes later each day, so roughly once a month it skips a calendar day.
