some dates fail to calculate, including today, for specific coordinates

[Quicksilver151]

    let params:Parameters = Configuration::with(Method::MuslimWorldLeague, Madhab::Shafi);
    let coordinates = Coordinates::new(3.12, 101.69);
    let schedule = PrayerTimes::new(Utc.ymd(2024, 4, 9), coordinates, params);

this code just straight up panics

[insha]

Thank you for submitting this issue. I have a fix ready and I am writing tests around it to make sure the fix is working and there are no regressions caused by it.

[Quicksilver151]

i had no idea that you fixed it. ive been sitting on making the tui salah app for ages lol. imma work on that now
