KHGT - Kalender Hijriah Global Tunggal wót DiengLabs

KHGT - Kalender Hijriah Global Tunggal puts the KHGT one click away in Chrome, Edge, and Firefox — glanceable, offline-first, and private by default.

• Today — the KHGT Hijri date and Gregorian date, the five daily prayer times (Subuh, Zuhur, Ashar, Maghrib, Isya) plus sunrise (Terbit), and a live countdown to the next prayer.
• New Tab dashboard (opt-in) — enable it to turn every new tab into a full-screen KHGT home screen (date, prayer times, countdown, mini-calendar) with a search box. Off by default (a plain search box until you turn it on in Settings).
• Convert — two-way Hijri↔Gregorian conversion. Out-of-range dates are clearly labelled as an estimate, never silently guessed.
• Calendar — a navigable month grid in either calendar, with holidays marked.
• Reminders — optional notifications for prayers (with a pre-offset), the new Hijri month, and holidays, with a choice of adhan/takbir/system sound.
• Offline-first — everything works with no network. Prayer times are computed on-device and match the official source within ±1 minute.
• Private by default — your location and data never leave your device unless you opt in to validation against the official source.
• Multilingual — Indonesian, English, and Arabic (right-to-left).

A desktop-browser companion to the official KHGT. Data is sourced from the official KHGT at khgt.muhammadiyah.or.id.
