About

What this site is

Hijri.online is a free, ad-supported Hijri date converter and Islamic calendar resource centred on Singapore. It runs entirely in your browser — no account, no tracking of personal data, no payment.

What it does

• Shows today's Hijri date in real time.
• Converts between Hijri and Gregorian dates instantly.
• Counts down to Singapore's Islamic public holidays — Hari Raya Aidilfitri and Hari Raya Aidiladha — and other key Islamic events such as Ramadan, Awal Muharram, and Maulidur Rasul.
• Supports three calendar standards: MUIS (Singapore), Wifaq/MABIMS (Southeast Asia), and Umm al-Qura (Saudi Arabia).
• Provides written guides on the Islamic calendar, Ramadan, and the Hari Raya celebrations.

Methodology

The Hijri conversion uses well-established algorithms tuned to each supported standard. MUIS dates follow the MABIMS criteria (minimum altitude 3°, elongation 6.4°) adopted in 2021. Where the algorithm and the official MUIS Takwim differ, the official Takwim takes precedence — please cross-check critical dates against the MUIS website.
