Terms of Use
Last updated: October 2026. By using TahajjudCalculator you accept these terms. They are written to be read, not just agreed to.
The service
TahajjudCalculator provides free online calculators and informational guides about the Islamic night prayer (Tahajjud). The calculators compute prayer-related times — including Maghrib, Fajr, the last third of the night, and Islamic midnight — from astronomical formulas, the location and calculation method you select, and standard published conventions.
Calculated times are estimates
Computed times are estimates based on the selected method and coordinates, and may differ by a small margin (typically about a minute) from the timetable of your local mosque or authority, whose schedule may use different conventions, rounding, or precautionary adjustments. For prayer, follow your local mosque's timetable where one exists. We work hard on accuracy — our verification process is described on How We Calculate — but we do not warrant that any calculated time is exact for your location, and we accept no liability for reliance on a calculated time in place of a local authoritative timetable.
Religious content
The guides on this site are educational summaries prepared with care and cited to their sources. They are not fatwas, and this site does not issue religious rulings. Where scholars differ, we aim to present the difference fairly; for a ruling on your own situation, consult a qualified scholar. Translations of Quran and hadith are renderings of meaning and may not capture every shade of the original Arabic.
Acceptable use and intellectual property
You may use the tools freely for personal purposes and link to any page. The site's text, design and generated illustrations are the property of TahajjudCalculator unless otherwise stated; you may quote brief excerpts with attribution and a link. Automated scraping that degrades the service, misrepresentation of calculated times as officially endorsed, and any unlawful use are prohibited.
Support, external services, and changes
Optional support payments are processed by third parties (Whop; JazzCash in Pakistan) under their own terms; support is voluntary, is not a purchase of any additional service, and does not change the free availability of the tools. External links are provided for convenience; we are not responsible for third-party content. We may update the site and these terms at any time; the current version always lives on this page.
