満年齢は、生年月日から選択した基準日までに経過した満年数・月数・日数で計算します。2000-10-31生まれの場合、2026-10-30時点では25年11か月30日、2026-10-31には26年0か月0日です。
韓国の伝統的な数え年は「基準年−出生年+1」で、生まれた時に1歳、毎年1月1日に1歳増えます。暦年齢は1を足さず、満年齢は誕生日を基準にします。2023-06-28以降、韓国の行政・民事では満年齢が原則ですが、個別の法令に別の規定がある場合はその規定に従います。
いいえ。選択した生年月日は、このブラウザ内で処理されます。アプリのバックエンドに送信されたり、保存されたりすることはありません。
経過した年・月・日単位の年齢、経過した合計日数と週数、星座、干支、世代、次の誕生日までのカウントダウン、人生のマイルストーンを表示します。
入力する日付はグレゴリオ暦です。基準日は初期状態ではブラウザの現地日付での今日になり、過去の日付を選んで当時の年齢を計算することもできます。合計日数は経過時間ではなく暦日で数えます。言語を変えても旧暦など別の暦の日付は変換しません。
このツールは年齢と誕生日カウントダウンを計算する際、平年は2月28日を使います。2000-02-29生まれは2025-02-28時点で25年0か月0日となり、うるう年は2月29日を使います。これはツールの計算規則です。法的な年齢要件は適用される規定を確認してください。
Hanoon Age Calculator
Hanoon is a Christian-founded brand identity shaped by the biblical vision of being kept as the apple of God’s eye and living before His gaze with grace, truth, reverence, and holiness.
Hanoon is a reverent digital platform rooted in the Christian faith, built on the biblical vision of being kept as the apple of God’s eye.
Our mission is to provide tools that help believers engage Scripture, worship, and everyday tasks with clarity and integrity.
Hanoon exists to serve the global church with digital tools that reflect the character of God: gracious, faithful, and attentive.
He found him in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye.
Keep me as the apple of the eye, hide me under the shadow of thy wings.
The primary meaning of Hanoon remains the biblical image of God’s eye, the apple of His eye, rooted in Deuteronomy 32:10 and Psalm 17:8.
As a welcome secondary sound resonance, the Korean name “하눈” can also sound like “하는” and opens toward active expressions such as 찬송하는, 통독하는, 기도하는, and 찬양하는. This secondary resonance enriches but never replaces the primary biblical meaning.
Official slogan: Hanoon — His gaze, our grace.
Poetic HANOON mnemonic, not the official slogan or a formal doctrinal formula: His Apple, Never Out Of Notice.
Hanoon holds together two truths: we are kept by God as precious in His sight, and we are called to live before God in truth, holiness, and reverence.
This dual meaning is essential. Hanoon is not only about comfort or being loved by God. It is also about accountability, integrity, purity, and a life lived consciously before Him.
Hanoon’s theological boundary is broadly Reformed, Evangelical, Presbyterian, historically confessional Protestant. Truth before trend. Reverence before spectacle. Grace without compromise. Holiness without harshness.
Holy Scripture is inspired, trustworthy, sufficient, and the final authority for faith and life. Hanoon affirms Sola Scriptura, Sola Gratia, Sola Fide, Solus Christus, and Soli Deo Gloria.
Jesus Christ is true God and true man, the only Savior and Mediator. Fallen people cannot save themselves; salvation comes through Christ’s life, death, and resurrection and is received by grace through faith, leading to repentance, humility, obedience, sanctification, holiness, and perseverance.
The Holy Spirit convicts, regenerates, sanctifies, illumines, comforts, empowers, and builds the church. Every spiritual claim and experience remains under the authority of Scripture.
Hanoon aims to be reverent, clear, intelligent, calm, grounded, and honest. The design system, navigation, content surfaces, and product tone should feel disciplined rather than showy.
Hanoon Age Calculator is one part of the wider Hanoon service family and follows the same product and brand contract.

Hanoon uses only the data needed to operate each service, keep sessions stable, protect the platform, and perform privacy-safe analytics or usage measurement. Eligible user routes begin with analytics storage enabled by default unless you have opted out; denied-storage traffic continues with provider-defined cookieless measurement.
Hanoon Age Calculator may process technical data that is required to deliver the site, keep sessions stable, protect the service, and measure product quality. Eligible user routes use analytics storage by default for continuity; after an explicit opt-out they continue with provider-defined cookieless measurements.
Depending on the service, this can include cookies and localStorage values, privacy-safe analytics or usage measurement, authentication or session data, media delivery requests, or messages that you intentionally submit through support flows.
Many Hanoon tools are designed to work primarily in the browser. When a tool can complete its job locally, your working content may remain on your device.
If a service needs third-party infrastructure such as authentication, storage, privacy-safe analytics or usage measurement, or form handling, only the data needed to operate that feature should be used.
On eligible user routes, approved analytics providers load immediately after private URL state is excluded. Analytics storage and cross-page or session continuity are enabled by default without a prompt. Turning analytics storage off returns measurement to denied cookieless or no-consent mode and removes supported provider cookies without disabling aggregate measurement.
File contents, file names, passwords, free-form tool input, and generated output are excluded from analytics. Hanoon may store your consent choice and other non-analytics session or preference values in cookies and localStorage, which you can review or clear through browser settings.
You can control theme and locale preferences through browser storage settings. You can also avoid submitting optional personal information through support or contact flows.
If you have a privacy question about Hanoon, use the main contact page and include the service name and URL in your message.
