About onomasti

Every Greek name has a day — a saint's feast the name comes from. onomasti finds yours, and lets you subscribe once to a calendar that keeps itself right, even for the ~20 feasts that move every year because they hang off Orthodox Easter.

What it does

Looks up any Greek name and shows every feast day kept for it — Greek custom often keeps more than one, and we show them all rather than guess a "winner."
Explains the anglicised names diaspora families actually use — a Gus, a Con, a Bill — and traces them back to the formal name and its feast (names' stories).
Lets you build a personal calendar feed (webcal / Google / Outlook) that resolves moving feasts correctly every year, forever, with no re-subscribing.

The badge/verification system

Nothing here is hand-labelled "verified." Every feast date carries a machine-derived badge:

✓ sourced — confirmed by two lineage-independent sources: two sources that don't derive from one another or a shared upstream text. A ✓ feast is safe to put in a calendar and appears in our subscription feeds.
⚠ unverified — not yet confirmed by two lineage-independent sources: either it rests on a single source, or the mapping is a judgment call we're holding until the printed synaxaria confirm it. Shown for reference, but held out of calendar feeds until confirmed. Low risk is not the same as verified, so we don't blur the two.

The same two-source-independence rule governs the anglicised-name pages: a ✓ alias is traced to a written source; a 🗣 alias is reported by families and shown as unverified until it earns a source.

Honest scope

This is a growing corpus, not an exhaustive one. 98 names are in it today, each with every feast marked ✓ or ⚠. New names, aliases and regional surname patterns are added only when they can be sourced properly — we'd rather ship a smaller, honest site than a bigger, guessed one.
