Sun times & shoot planning
Scored across 3 tools
Each tool has a distinct role: single-date solar/twilight lookup, day-length comparison, and multi-day shoot planning with exports. The only overlap is day-length and golden-hour data appearing across tools, but descriptions make the intended use clear.
All names are snake_case, verb-first, and use domain-specific nouns. plan_golden_hour_shoot is longer but still follows the same predictable convention.
Three tools are tightly scoped to a narrow golden-hour and sun-times domain, with no redundant entries. The small set fits the focused purpose and each tool earns its place.
Coverage includes single-date sun/twilight data, cross-date day-length comparison, and date-range shoot planning with calendar/CSV output. Gaps are minor: no city/geocoding lookup or coordinate-based input, but core workflows are covered.
Use this when the user asks for day length differences and average change per day between two local dates, or the solstices and equinoxes of a year. Returns daylight duration for each date and signed changes. Limits: cities with population 50,000+ (plus Tromso), dates/years 1900–2100, flat sea-level horizon; use either date_a and date_b or year, and not both. Does not forecast weather.
Inputs: city (required), year, state, date_a, +2 more. Returns: blue, date, days, mode, +24 more
Use this when the user asks for a golden hour calculator, golden hour time, sunrise sunset times, sunset time today, what time is golden hour, blue hour, sunrise time, or twilight times for a city and local date. Returns local sunrise, sunset, solar noon, day length, twilight, light windows and sun azimuth. Limits: cities with population 50,000+ (plus Tromso), dates 1900–2100, flat sea-level horizon; Does not model weather or terrain.
Inputs: city (required), date (required), state, country. Returns: blue, date, days, mode, +24 more
Use this when the user wants photography golden hour shoot windows for a city and a date range, with an ICS calendar file and CSV table. Choose morning, evening or both. Limits: 1–31 days, cities with population 50,000+ (plus Tromso), years 1900–2100, flat sea-level horizon; missing polar windows are reported and calendar events are only included for existing windows. Does not access or change a calendar.
Inputs: city (required), days (required), period (required), start_date (required), +2 more. Returns: blue, date, days, mode, +24 more
