    Why it is in this group

    • The name "get_sun_times" says "get": a word for reading.
    Description, as the server wrote it
    Sunrise, sunset, solar noon, day length, civil/nautical/astronomical twilight, dawn/dusk, first/last light, golden hour, blue hour, sunrise/sunset azimuth, solar noon altitude, moonrise/moonset, moon phase and illumination for any coordinates on Earth and any date. Times are ISO 8601 in the local timezone of the location. Polar day/night handled via sun_status (normal | midnight_sun | polar_night); events that do not occur are null.

    Why it is in this group

    • The name "get_sun_times_range" says "get": a word for reading.
    Description, as the server wrote it
    Same per-day data as get_sun_times but for an inclusive date range (up to 366 days) in a single call. Use this instead of repeated get_sun_times calls when you need several consecutive days. The days array may contain fewer entries than the number of dates requested: calendar days that never existed in that timezone (Samoa skipped 30 December 2011 when it crossed the date line) are left out, so read each entry's date field instead of assuming one per requested date.

    Annotations the server declares

    • title: Sunrise & sunset times for a date range
    • readOnlyHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
