Sunrise time calculator
What time does the sun come up?
Pick a city and a date for the sunrise in local clock time, with sunset and day length, then scan the first day of every month for the year ahead.

First day of each month
How the sunrise time is worked out
The calculator uses a standard solar position method. It works out the sun’s declination for the date, the time of solar noon for the city’s longitude, and the hour angle at which the sun reaches the horizon. The result is shown in the city’s local clock time, so daylight saving is handled automatically for that date.
Why plan around sunrise
Early hikes, sunrise photography, fishing trips, the first flight of the day and mornings at a lake all depend on when the light comes up. Check the date you need, then add travel time and a buffer for twilight. Sunrise is a few minutes later each day in some seasons and earlier in others, so the monthly view helps when you plan ahead.
Figures come from a standard formula and can differ from official almanacs by a minute or two. Check a local almanac or weather service before an early start.
Plan the light, not just the day

Sunrise questions
How do I find the sunrise time for my city?
Choose a city from the list and a date. The sunrise time appears in local clock time for that date, with sunset and day length beside it.
Does this account for daylight saving time?
Yes. Times are shown in the chosen city’s local clock, so the daylight saving change is included for that date.
Why does sunrise change through the year?
The earth is tilted, so the length of day and the time of sunrise change with the seasons. In many northern places sunrise is latest in early winter and earliest in early summer.
Is this as accurate as an almanac?
It is a planning estimate using a standard formula, usually within a minute or two. For an exact time on a critical day, compare it with an official almanac.
