    There are 60 minutes on an analog clock.
    There are 12 hours on an analog clock.

    Also note that if it's 5:30, the hours hand isn't on the 5. It's halfway between 5 and 6.
    There are also 60 minutes between each hour, of which there are 12.
    Hence, the math used here. Ask if you need explanation.

local function findAngle(hours, minutes)
    -- The angle of the hours hand
    local hAngle = (hours / 12) * 360 + (minutes / (12 * 60)) * 360
    -- The angle of the minutes hand
    local mAngle = (minutes / 60) * 360
    -- The angle between them - absolute value
    local angle = math.abs(hAngle - mAngle)

    -- There's a larger angle and a smaller angle - return the smallest
    return angle > 180 and 360 - angle or angle
