Who We Are & Our Role in Zetawala
Hasiba (حاسبة) is a premier calculation utility platform specifically built to provide free, high-speed, and audited digital calculators for users across Saudi Arabia, the United Arab Emirates, Egypt, and the wider Gulf and Arab region.
Hasiba was developed as a flagship project of the Zetawala Network, an independent digital technology initiative focused on engineering open, free-to-use, and privacy-respecting online utilities. Our core conviction is that essential calculations—whether for labor entitlements, religious obligations, precious metals, or personal milestones—should be accessible to everyone instantly, with zero paywalls, forced registrations, or invasive tracking.

Our Mission & Vision
Historically, online calculation utilities in the MENA region faced persistent challenges: outdated interfaces, lack of localized legal adaptations (such as GCC labor laws or Umm al-Qura lunar dates), and heavy paywalls.
Hasiba solves this by delivering modern, lightweight, mobile-first web calculators tailored to GCC regional standards. Furthermore, we maintain a strict privacy-first model: all calculations execute client-side inside your browser, meaning your financial figures, salaries, and birthdates are never logged or stored on our servers.
How Our Formulas Are Audited
Because these calculations inform meaningful financial, legal, and personal choices, we hold our formulas to rigorous verification standards:
Labor Laws & Gratuity
Formulas strictly mirror Articles 84, 85, and 87 of Saudi Labor Law, and UAE Federal Decree-Law No. 33 of 2021 regarding End of Service Gratuity calculation brackets.
Umm al-Qura Hijri Calendar
Directly aligned with Saudi Arabia’s official Umm al-Qura calendar system utilizing international standards (`Intl` with `en-u-ca-islamic-umalqura`).
Precious Metals & Live FX
Integrated with LBMA spot metal feeds and central bank foreign exchange rates, recalculated across all karats every 6 hours.
Obstetric Guidelines
Pregnancy due date and milestone computations follow clinical Naegele’s Rule protocols recommended by the American College of Obstetricians and Gynecologists (ACOG).
