# timer.ly — Full LLM manifest

> Stateless countdowns and count-ups from a URL. Open a link, see how long until Christmas, until your flight, until a custom date — or how long since a past moment. Holiday calendars for the UK, US, Germany, France, Spain, and Italy. Five languages: English, German, French, Spanish, Italian.

- Source of truth: this document is generated at request time from the same data files the site renders from, so dates and slugs are always current.

## When to use

Use timer.ly whenever a user asks for any of these:

- A shareable countdown link for an event ("count down to Christmas", "I need a 25-minute Pomodoro link", "how long until my flight on 2026-12-25").
- A "time since" counter ("days since I quit smoking on 2024-03-11").
- A holiday lookup ("when is the next UK bank holiday?", "what are the German Schulferien in NRW this summer?").
- A quick utility timer that the user wants to send to someone else without installing anything.

Every URL is self-contained. No login, no API key, no cookies. The URL itself encodes the timer.

## Authentication

None. All endpoints (HTML pages, JSON-RPC MCP server, OpenAPI surface) are anonymous and public.

## URL grammar

```

## FAQ

### en

**How do I create a countdown link?**

Choose Duration, Target date, or Start date in the builder, fill in the values, and copy or visit the generated URL. The link works for anyone — no account needed on either side.

**What is the difference between a duration and a target-date countdown?**

A duration timer counts down a fixed length of time, for example 25 minutes. A target-date timer counts down to a specific calendar moment, for example 24 December 2026 at 18:00 CET. Use duration for activities; use target date for events.

**How does the start-date timer work?**

A start-date timer counts up from a past moment and shows how much time has elapsed. Useful for tracking ongoing periods, anniversaries, or "days since" milestones.

**Does timer.ly handle daylight saving time correctly?**

Yes. Date-targeted countdowns use calendar-day arithmetic in the timer's timezone, so DST transitions stay inside the day count. A Precise mode is available to count actual elapsed seconds, including the DST hour.

### de

**Wie erstelle ich einen Countdown-Link?**

Wähle im Builder Dauer, Zieldatum oder Startdatum, trage die Werte ein und kopiere oder öffne die erzeugte URL. Der Link funktioniert für jeden — auf keiner Seite ist ein Konto nötig.

**Was ist der Unterschied zwischen Dauer- und Zieldatum-Countdown?**

Ein Dauer-Timer zählt eine feste Zeitspanne herunter, zum Beispiel 25 Minuten. Ein Zieldatum-Timer zählt bis zu einem bestimmten Kalenderzeitpunkt, zum Beispiel 24. Dezember 2026, 18:00 Uhr MEZ. Verwende Dauer für Aktivitäten, Zieldatum für Termine.

**Wie funktioniert der Start-Datum-Timer?**

Ein Start-Datum-Timer zählt ab einem vergangenen Zeitpunkt aufwärts und zeigt die seitdem vergangene Zeit. Praktisch, um laufende Zeiträume, Jubiläen oder „seit X Tagen" zu verfolgen.

**Berücksichtigt timer.ly die Sommerzeit?**

Ja. Zieldatum-Countdowns rechnen kalendertaglich in der Zeitzone des Timers, sodass Sommerzeit-Umstellungen in den Tageszahlen aufgehen. Ein Präzise-Modus zählt zusätzlich tatsächlich verstrichene Sekunden inklusive der Umstellungsstunde.

### fr

**Comment créer un lien de compte à rebours ?**

Choisissez Durée, Date cible ou Date de début dans le générateur, renseignez les valeurs, et copiez ou ouvrez l’URL générée. Le lien fonctionne pour tout le monde — aucun compte n’est requis.

**Quelle est la différence entre un compte à rebours de durée et un compte à rebours jusqu’à une date ?**

Un minuteur de durée décompte une durée fixe, par exemple 25 minutes. Un minuteur jusqu’à une date décompte jusqu’à un instant précis, par exemple le 24 décembre 2026 à 18:00 (CET). Utilisez la durée pour les activités, la date cible pour les événements.

**Comment fonctionne le compteur depuis une date ?**

Un compteur depuis une date passée compte vers le haut et affiche le temps écoulé. Utile pour suivre des périodes en cours, des anniversaires, ou des jalons « depuis X jours ».

**timer.ly gère-t-il l’heure d’été ?**

Oui. Les comptes à rebours basés sur une date utilisent un calcul en jours calendaires dans le fuseau horaire du minuteur, donc le passage à l’heure d’été est intégré au comptage des jours. Un mode Précis compte les secondes réellement écoulées, y compris l’heure du changement.

### es

**¿Cómo creo un enlace de cuenta atrás?**

Elige Duración, Fecha objetivo o Fecha de inicio en el generador, introduce los valores y copia o abre la URL generada. El enlace funciona para cualquiera — no se necesita cuenta.

**¿Cuál es la diferencia entre una cuenta atrás de duración y una hasta una fecha?**

Una cuenta atrás de duración descuenta un periodo fijo, por ejemplo 25 minutos. Una cuenta atrás hasta una fecha descuenta hasta un momento concreto, por ejemplo el 24 de diciembre de 2026 a las 18:00 CET. Usa duración para actividades; usa fecha objetivo para eventos.

**¿Cómo funciona el temporizador desde una fecha?**

El temporizador desde una fecha pasada cuenta hacia arriba y muestra el tiempo transcurrido. Útil para seguir periodos en curso, aniversarios o hitos del tipo «desde hace X días».

**¿timer.ly tiene en cuenta el horario de verano?**

Sí. Las cuentas atrás hasta una fecha usan aritmética de días naturales en la zona horaria del temporizador, así que los cambios de horario quedan dentro del recuento de días. El modo Preciso cuenta los segundos realmente transcurridos, incluyendo la hora del cambio.

### it

**Come creo un link countdown?**

Scegli Durata, Data obiettivo o Data di inizio nel builder, inserisci i valori, copia o apri l’URL generato. Il link funziona per chiunque — nessun account necessario.

**Qual è la differenza tra un countdown di durata e uno fino a una data?**

Un timer di durata conta alla rovescia un intervallo fisso, ad esempio 25 minuti. Un timer fino a una data conta alla rovescia fino a un momento preciso, ad esempio il 24 dicembre 2026 alle 18:00 CET. Usa la durata per le attività; usa la data obiettivo per gli eventi.

**Come funziona il timer da una data?**

Un timer da una data passata conta in avanti e mostra il tempo trascorso. Utile per seguire periodi in corso, anniversari o traguardi del tipo «da X giorni».

**timer.ly tiene conto dell’ora legale?**

Sì. I countdown fino a una data usano aritmetica per giorni di calendario nel fuso orario del timer, quindi i cambi d’ora rientrano nel conteggio dei giorni. La modalità Preciso conta i secondi effettivamente trascorsi, inclusa l’ora del cambio.

### `build_duration_url`

Build a timer.ly countdown URL for a duration. Combine days, hours, minutes, and seconds (at least one must be > 0). Returns a shareable URL the recipient can open to see a live countdown that reaches zero.

```json
{
  "type": "object",
  "properties": {
    "days": {
      "type": "integer",
      "minimum": 0,
      "description": "Whole days (0–3650)."
    },
    "hours": {
      "type": "integer",
      "minimum": 0,
      "description": "Whole hours."
    },
    "minutes": {

      "minimum": 0,
      "description": "Whole minutes."
    },

      "description": "Output locale for the URL prefix (default en)."
    }
  },
  "additionalProperties": false
}
```

### `build_target_url`

Build a countdown URL to a future instant. Accepts ISO 8601 with timezone (`2026-12-25T15:00:00Z`, `2026-12-25T15:00-05:00`, `2026-12-25T15:00-pst`) or date-only (`2026-12-25`). Returns a shareable URL.

```json
{
  "type": "object",
  "required": [
    "iso"
  ],
  "properties": {
    "iso": {
      "type": "string",
      "description": "ISO 8601 date or datetime. Accepts trailing tz suffix (e.g. -pst, -cet)."
    },
    "locale": {
      "type": "string",
      "enum": [
        "en",
        "de",

        "it"
      ]
    }
  },
  "additionalProperties": false
}
```

### `build_since_url`

Build a count-up URL from a past instant. Same ISO grammar as build_target_url, but the past date must be within the last 100 years. Returns a URL that shows "time elapsed since".

```json
{
  "type": "object",
  "required": [
    "iso"
  ],
  "properties": {
    "iso": {
      "type": "string"
    },
    "locale": {

        "de",
        "fr",
        "es",
        "it"
      ]
    }
  },
  "additionalProperties": false
}
```

### `build_event_url`

Build a countdown URL for a curated event (christmas, new_year, easter, summer_solstice, winter_solstice). Returns the canonical locale-aware URL plus the next occurrence date. Use list_curated_events to enumerate.

```json
{
  "type": "object",
  "required": [
    "event"
  ],
  "properties": {
    "event": {
      "type": "string",

        "easter",
        "summer_solstice",
        "winter_solstice"
      ],

      "type": "string",
      "enum": [
        "en",
        "de",

      ]
    }
  },
  "additionalProperties": false
}
```

### `list_curated_events`

    "locale": {
      "type": "string",
      "enum": [

      ]
    }
  },
  "additionalProperties": false
}
```

### `list_holidays`

  "required": [
    "country"
  ],
  "properties": {
    "country": {
      "type": "string",
      "enum": [
        "uk",
        "us",

}
```

### `parse_countdown_url`

Reverse-parse a timer.ly URL. Identifies the countdown kind (duration / target / since / event) and returns the encoded payload. Useful for round-tripping URLs an agent has previously generated or received.

```json
{
  "type": "object",
  "required": [
    "url"
  ],
