نه منظورم کد اصلی برنامه است
یعنی همون سینوس کسینوسها و ... که هنگام نماز صبح و ظهر مشخص میشه چیه
یا بهتر بگم الگوریتم اوقات شرعی برای بسکام می خوام
یعنی شما فرمول خود محاسبات اوقات شرعی رو بزارین ممنون میشم
من دانشجوی کارشناسی ترم آخرم و برای ساخت تابلوی اوقات شرعی یه چیزی تو مایه های ساعت حرم می خوام که در واقع هنگام اذان خودش اذان بگه یعنی کلا کد اوقات شرعی رو می خوام که چطور محاسبه میشه
البته به زبان ساده و لطفا سایت معرفی نکنیین همه رو گشتم بدردم نخورد
مثلا تو لینک زیر یه الگوریتمی هست برای محاسبات هست اگه الگوریتم برنامه شما هم این است یه توضیح و مثالی برای اون بدین ممنون میشم
سایتی که گفتم>>>>>>>>>>>>>>

اگه آقایی کنی و اگر از فرمول زیر چیزی سردر آوردی یه مثال کامل ازش بزن ممنونتان
d = jd - 2451545.0; // jd is the given Julian date
مثلا jd رو چطور و به چه فرمتی باید نوشت
g = 357.529 + 0.98560028* d;
q = 280.459 + 0.98564736* d;
L = q + 1.915* sin(g) + 0.020* sin(2*g);
R = 1.00014 - 0.01671* cos(g) - 0.00014* cos(2*g);
e = 23.439 - 0.00000036* d;
RA = arctan2(cos(e)* sin(L), cos(L))/ 15;
مثلا خط بالا چطوریه و چی میشه منظورم اون ,علامت < , > نقشش چیه
D = arcsin(sin(e)* sin(L)); // declination of the Sun
EqT = q/15 - RA; // equation of time
[h=2]Calculating Prayer Times[/h]To calculate the prayer times for a given location, we need to know the latitude (L) and the longitude (Lng) of the location, along with the local Time Zone for that location. We also obtain the equation of time (EqT) and the declination of the Sun (D) for a given date using the algorithm mentioned in the previous section.
[h=3]Dhuhr[/h]Dhuhr can be calculated easily using the following formula:
Dhuhr = 12 + TimeZone - Lng/15 - EqT.
The above formula indeed calculates the midday time, when the Sun reaches its highest point in the sky. A slight margin is usually considered for Dhuhr as explained in
this note.
[h=3]Sunrise/Sunset[/h]The time difference between the mid-day and the time at which sun reaches an angle α below the horizon can be computed using the following formula:
Astronomical sunrise and sunset occur at α=0. However, due to the refraction of light by terrestrial atmosphere, actual sunrise appears slightly before astronomical sunrise and actual sunset occurs after astronomical sunset. Actual sunrise and sunset can be computed using the following formulas:
Sunrise = Dhuhr - T(0.833),
Sunset = Dhuhr + T(0.833).
If the observer's location is higher than the surrounding terrain, we can consider this elevation into consideration by increasing the above constant 0.833 by 0.0347 × sqrt(h), where h is the observer's height in meters.
[h=3]Fajr and Isha[/h]There are differing opinions on what angle to be used for calculating Fajr and Isha. The following table shows several conventions currently in use in various countries (more information is available at
this page).
| Convention | Fajr Angle | Isha Angle |
|---|
| Muslim World League | 18 | 17 |
| Islamic Society of North America (ISNA) | 15 | 15 |
| Egyptian General Authority of Survey | 19.5 | 17.5 |
| Umm al-Qura University, Makkah | 18.5 | 90 min after Maghrib
120 min during Ramadan |
| University of Islamic Sciences, Karachi | 18 | 18 |
| Institute of Geophysics, University of Tehran | 17.7 | 14* |
| Shia Ithna Ashari, Leva Research Institute, Qum | 16 | 14 |
* Isha angle is not explicitly defined in Tehran method.
For example, according to Muslim World League convention, Fajr = Dhuhr - T(18) and Isha = Dhuhr + T(17).
[h=3]Asr[/h]There are two main opinions on how to calculate Asr time. The majority of schools (including Shafi'i, Maliki, Ja'fari, and Hanbali) say it is at the time when the length of any object's shadow equals the length of the object itself plus the length of that object's shadow at noon. The dominant opinion in the Hanafi school says that Asr begins when the length of any object's shadow is twice the length of the object plus the length of that object's shadow at noon.
The following formula computes the time difference between the mid-day and the time at which the object's shadow equals
t times the length of the object itself plus the length of that object's shadow at noon:
Thus, in the first four schools of thought, Asr = Dhuhr + A(1), and in Hanafi school, Asr = Dhuhr + A(2).
[h=3]Maghrib[/h]In the Sunni's point of view, the time for Maghrib prayer begins once the Sun has completely set beneath the horizon, that is, Maghrib = Sunset (some calculators suggest 1 to 3 minutes after Sunset for precaution). In the Shia's view, however, the dominant opinion is that as long as the redness in the eastern sky appearing after sunset has not passed overhead, Maghrib prayer should not be performed. It is usually taken into consideration by assuming a twilight angle like Maghrib = Dhuhr + T(4).
[h=3]Midnight[/h]Midnight is generally calculated as the mean time from Sunset to Sunrise, i.e., Midnight = 1/2(Sunrise - Sunset). In Shia point of view, the juridical midnight (the ending time for performing Isha prayer) is the mean time from Sunset to Fajr, i.e., Midnight = 1/2(Fajr - Sunset).
[h=2]Higher Latitudes[/h]In locations at higher latitude, twilight may persist throughout the night during some months of the year. In these abnormal periods, the determination of Fajr and Isha is not possible using the usual formulas mentioned in the previous section. To overcome this problem, several solutions have been proposed, three of which are described below.
Middle of the Night In this method, the period from sunset to sunrise is divided into two halves. The first half is considered to be the "night" and the other half as "day break". Fajr and Isha in this method are assumed to be at mid-night during the abnormal periods. One-Seventh of the Night In this method, the period between sunset and sunrise is divided into seven parts. Isha begins after the first one-seventh part, and Fajr is at the beginning of the seventh part. Angle-Based Method This is an intermediate solution, used by some recent prayer time calculators. Let α be the twilight angle for Isha, and let
t = α/60. The period between sunset and sunrise is divided into
t parts. Isha begins after the first part. For example, if the twilight angle for Isha is 15, then Isha begins at the end of the first quarter (15/60) of the night. Time for Fajr is calculated similarly. In case Maghrib is not equal to Sunset, we can apply the above rules to Maghrib as well to make sure that Maghrib always falls between Sunset and Isha during the abnormal periods.
در کل مظورم همون الگوریتم کلی محاسبات زمان شرعی هست
