    Comment/Request
    Want to know how to calculate it for my location
    [6]  2020/02/27 01:35   Male / 40 years old level / A teacher / A researcher / Very /
    Purpose of use
    Calculate sunrise considering observer elevation (at the top of a montain vs at sea level)
    [7]  2020/01/19 19:45   Male / 50 years old level / An office worker / A public employee / Very /
    Purpose of use
    To know when I can get outside to work or walk, and for how much daylight I may have inthe evening when home to work or walk.
    Comment/Request
    Very useful and accurate, thank you!
    [8]  2019/12/27 05:25   Male / 60 years old level or over / Others / Useful /
    Purpose of use
    I make an annual calendar showing sun and moon rise and set times and share it with local astronomers. I need an annual table for the whole year for a particular location.
    Comment/Request
    I've been getting this data from the Naval Observatory for years. Suddenly their site is down for 'maintenance' and won't be back until mid 2020. What's that about?

    Purpose of use
    To check home outside light electronic automatic switch operation where switch is configured "on" sunset and "off" sunrise

    Purpose of use
    I have solar panels and wish to relate their output with Sun´s position and temperature
    Comment/Request
    One suggestion for improvement as an end-user:

    For a given (latitude, longitude), I´d like having a table for the whole year with:
    - solar culmination [already exists]
    - solar elevation [did not find]
    - solar azimuth at solar culmination [I guess that with the available equation of time, I can work that out]
    - time of sunrise
    - azimuth of sunrise
    - time of sunset
    - azimuth of sunset

    Great tool. Best wishes
