About SunriseAlmanac

SunriseAlmanac is a free reference for the daily movements of the sun and moon. For roughly 10,000 cities and towns in the United States, the United Kingdom, Canada, Australia, New Zealand and Ireland, it lists sunrise and sunset, twilight, golden hour and blue hour, moonrise and moonset, moon phases, the dates of the solstices and equinoxes, and the local daylight saving time changes.

Who it is for

The site is built for anyone whose plans depend on daylight: photographers timing a shoot for golden hour or blue hour, runners and cyclists who want to finish before dark, hikers and anglers, gardeners, parents planning an evening at the park, people adjusting to the clock change, and anyone who is simply curious why the evenings feel longer in one city than another.

What is on a city page

Every place has its own page, and every figure on it is shown in that place's local time, including daylight saving time when it applies. A city page includes:

  • Today: sunrise, sunset, day length, and the start and end of civil, nautical and astronomical twilight.
  • Golden hour and blue hour: the morning and evening windows, with start and end times.
  • The moon: moonrise, moonset, the current phase and how much of the disk is lit.
  • A 7-day outlook: the coming week at a glance, useful for planning around a particular evening.
  • Month and year tables: sunrise, sunset and day length for every day, so you can see how the light changes across the seasons.

Separate pages cover the moon phase calendar, the solstices and equinoxes and the daylight saving time dates for each year.

Coverage

SunriseAlmanac covers six English-speaking countries and about 10,000 places, from large metropolitan areas to small towns. Place names, coordinates, populations and time zones come from GeoNames, the open geographical database. If a town you need is missing, or appears in the wrong place, please let us know.

How the figures are calculated

Nothing on the site is copied from another table. Every time is computed on our server from published astronomical algorithms, chiefly those in Jean Meeus's "Astronomical Algorithms", the same formulation that underlies the NOAA solar calculator. Time zones and daylight saving rules come from the IANA time zone database. The methodology page explains exactly how each figure is produced, which definitions we use and where the limits of accuracy lie. If a term is unfamiliar, the glossary explains it in plain language.

How the site is funded

SunriseAlmanac is free to use and does not require an account. It is supported by advertising served through Google AdSense. You can choose whether to allow personalized ads and optional analytics through the consent banner; the privacy policy describes what is and is not collected.
