    "longDescription": "Find golden hour, blue hour, sunrise, sunset and twilight for any place and date, computed with the NOAA solar algorithm, with a chart of the sun's height through the day.\n\nAsk \"when is golden hour in Santorini tomorrow\", \"sunset time in Paris on October 15\" or \"golden hours in Iceland for my trip next week\". The card leads with the next golden hour, then sunrise, sunset, day length and solar noon, every twilight phase from astronomical dawn to dusk, the moon phase, and a chart of the sun's elevation with the golden and blue hour bands. For a trip (up to 31 days) you get a day-by-day table. Polar day and night are handled.\n\nDownload the golden hours as calendar events so your phone reminds you before the light is best. Times are rounded to the minute and assume a flat horizon. Nothing is stored.",
