This presentation introduces a software calculator that determines the prayer times for Fajr, Dhuhr, Asr, Maghrib, and Isha, as well as sunset, based on latitude, longitude, and time zone inputs for a given location and date. The presentation demonstrates the calculator by inputting coordinates for Dhaka, Bangladesh on June 10, 2018 and displaying the resulting prayer times. It notes there may be minor deviations for some times that need further refinement.
