Horafold — Timezone & Calendar Converter

Horafold makes dates and times on the web feel local. Enable it for a site, tell Horafold which timezone and calendar the page uses, and choose the timezone and calendar you want to see. Conversion happens directly in your browser. Highlights: • Convert times with daylight-saving-aware IANA timezone rules. • Translate dates between Gregorian, Jalali / Solar Hijri, Hijri, Buddhist, Indian national, Minguo, Japanese, Coptic, Ethiopic, and other supported calendars. • Keep the page's familiar formatting—including separators, field order, 12/24-hour style, AM/PM markers, and Persian or Arabic-Indic digits. • Replace dates and times inline or leave the original text in place and see conversions on hover. • Recognize common ISO, numeric, written-month, Chinese, and Persian date/time formats, including ranges. • Save different choices for different sites, with optional defaults for new sites. • Restore the original page instantly when you turn Horafold off—no reload required. Privacy by design: Horafold has no ads, analytics, tracking, or developer-controlled network requests. Page content is processed locally. Only your extension preferences are saved through Chrome Sync. How to use Horafold: 1. Open a webpage and select the Horafold toolbar icon. 2. Turn Horafold on for that site. 3. Choose what the page uses and what you want to see. Horafold stays off on each site until you enable it there.
