Accurate sunrise and sunset times

  How people use Suncurves

I was excited to find your service. I am a wedding photographer and had a client asking what would be the best time for her wedding ceremony, in relation to the photographs we'd be doing after the ceremony. She wanted to be sure we had the best light possible for her bride and groom photos. The ceremony will take place just below a mountain top, where the sun can go "down" long before the actual sunset time. Your service was very helpful in determining the best time for my client's ceremony and photos, which is so important for photographers!

I used Suncurves to create a schedule for myself in 2015. My goal is to wake up "with the sun" each day to get my body’s circadian rhythm synchronized with daylight-based zeitgebers help me get better sleep. Suncurves tells me when the sun will get up tomorrow. So I set myself a bedtime alarm for visible sunrise minus 9 hours to ensure I am getting a solid 8 hours of sleep each night. Suncurves is helping me achieve my health goals!

I am using SunCurves to assess the amount of sunlight a parcel of potential agricultural land has. The land has a slight slope and we are unsure if it will receive enough sunlight between April and August to grow crops.

I'm an amateur astronomer, I am trying to find a very accurate terrain profile for my city, useful to input that in an astronomy software and then be able to calculate the times at which the principal stars below the horizon will rise and set.

  Why use Suncurves?

Are you selling a house in a sunny spot with marginal terrain or mountain shading effects? We can help you get a higher price for that house by documenting its sun index. Or if you're looking to buy a house, wouldn't you like to know its exact sunlight conditions throughout the year? We have developed a unique method to compute the accurate sunrise and sunset times for every day of the year. The sunrises and sunsets we compute are not the ones you would find elsewhere on the web, because other sites do not take the terrain into account. Our sunrise is when the sun goes up from behind mountains or hills in the east, not when it goes up over the level horizon. In mountainous regions that can make a huge difference. We also compute the monthly mean cloud cover based on satellite data.
