How This Works — Islamic Tools — Prayer Times, Zakat, Hijri Calendar, and More
The HashmiTools Islamic section provides a collection of free tools designed for the practical needs of Muslim users worldwide, with particular relevance for Pakistani, Indian, and Gulf-based communities: accurate prayer times using multiple calculation methods, Hijri/Gregorian calendar conversion, Zakat calculation, Qurbani planning, and Umrah preparation.
How Prayer Times Are Calculated: Accurate prayer times depend on your geographical location (latitude and longitude) and the calculation method used by your local religious authority. Different methods use different solar angle definitions for Fajr and Isha — the two prayers calculated by the sun's position below the horizon rather than its direct visibility. The Karachi method (18° Fajr, 18° Isha) is standard for Pakistani and South Asian users; the Muslim World League method (18° Fajr, 17° Isha) is used in Europe and North America; the Egyptian General Authority method (19.5° Fajr, 17.5° Isha) is used in Egypt and the Gulf. The Prayer Times tool uses the Aladhan API to deliver precise, location-based times using your chosen method. Other tools in this section: Hijri Converter (convert between Islamic and Gregorian calendar dates); Zakat Calculator (2.5% of zakatable assets above nisab, Hanafi methodology); Qurbani Calculator (per-share cost for Eid al-Adha sacrifice); Plan Umrah (10-step preparation wizard); and Inheritance Calculator (Islamic Fara'idh distribution).
Frequently Asked Questions
Which prayer time calculation method should I use in Pakistan?
For Pakistan, the University of Islamic Sciences, Karachi method is the standard reference used by the majority of mosques and religious institutions. This method uses 18° for both Fajr and Isha angles, which produces prayer times consistent with traditional Pakistani religious practice. The Pakistan government's Ministry of Religious Affairs also publishes official prayer time tables using this method. If you find discrepancies between our calculated times and your local mosque's announced times, ensure you are using the Karachi method and have entered your precise city coordinates — Pakistan spans multiple time zones and latitude ranges, and even within one city, minor coordinate differences can shift prayer times by a few minutes.
Is the Hijri calendar conversion accurate?
The Hijri calendar is a lunar calendar of 354–355 days per year, approximately 11 days shorter than the Gregorian solar calendar. Conversion between the two calendars is algorithmic — the standard Tabular Islamic Calendar (used for historical and administrative purposes) is calculated mathematically and is precisely accurate. However, the actual beginning of each Hijri month (and therefore exact dates for Ramadan, Eid, etc.) in traditional Islamic practice depends on physical sighting of the new moon (hilal), which varies by location and religious authority. The Converter uses the standard astronomical calculation, which aligns with most countries' officially announced dates but may differ by 1 day from moon-sighting-based rulings in some regions or communities.
How do I calculate Zakat on investments, gold, and business inventory?
Zakat is due on specific categories of zakatable assets: gold and silver (at their current market value); cash and bank balances; trade goods and business inventory (at their current market value, not cost price); receivables (money owed to you that you expect to recover); and shares in companies (typically calculated on the per-share market value, with some scholars calculating only on the zakatable assets of the underlying company). Assets excluded from Zakat include: personal residence, personal vehicle, household goods, and business equipment used in production (not for sale). The Zakat Calculator guides you through each category with clear prompts, then applies the 2.5% rate to your net zakatable assets above the nisab threshold.
