+# praycalc
+
+Prayer times calculator using nrel-spa and custom formula for Fajr and Isha angles (as well as traditional static angle methods in the All function).
+
+## Installation
+
+```bash
+npm install praycalc
+```
+
+## Usage
+
+Example of using praycalc to get prayer times:
+
+```js
+const { calcTimes } = require('./calcTimes');
+
+const date = new Date();   // Current date
+const latitude = 40.7128;  // Latitude for New York City
+const longitude = -74.006; // Longitude for New York City
+const elevation = 10;      // Elevation for New York City
+
+const prayerTimes = calcTimes(date, latitude, longitude, elevation);
+console.log(prayerTimes);
+```
+
+Exported functions include getTimes, calcTimes, getTimesAll, calcTimesAll where the "get" functions return fractal or decimal times directly from the source nrel-spa calculator and the "calc" functions return formatted times in HH:MM:SS.sss format.  The functions will give results including our custom angle but the "All" functions will include a methods key with all traditional static angle methods (Muslim World League, Egyptian General Authority of Survey, ISNA, etc.) included as well for their Fajr and Isha times.
+
+### Parameters:
+
+- date: The date for which prayer times are calculated.
+- lat: Latitude of the location.
+- lng: Longitude of the location.
+- elevation: Elevation in meters (optional, default 50).
+- temperature: Temperature in Celsius (optional, default 15).
+- pressure: Atmospheric pressure in millibars (optional, default 1013.25).
