Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Moon Phase and Lunar Calendar Get a clean, day by day lunar calendar for any date range and any place on Earth. This actor returns the moon phase, the percent illuminated, the moon's age, its distance from Earth, the exact times of new, first quarter, full, and last quarter moons, and optional moonrise and moonset for a location you choose. Everything is computed offline from a built in ephemeris. There is no API to call, no key to manage, and no website to scrape, so results are fast and the tool keeps working without maintenance. ### What you get One row per day with these fields: - date and weekday - phase emoji and phase name, from new moon through waning crescent - illumination as a percentage - moon age in days since the last new moon - distance from Earth in kilometres - principal phase and its exact time, on the days a new, first quarter, full, or last quarter moon occurs - moonrise and moonset for your latitude and longitude, when you ask for them Days with no moonrise or no moonset, which happen about once a month, are left blank rather than guessed. ### Who uses it Gardeners and planting calendars that follow the lunar cycle. Anglers timing trips around the moon. Photographers planning full moon and dark sky shoots. Event and wedding planners who want to know how bright the night will be. Anyone building a calendar app or almanac that needs reliable phase data. ### Input All fields have sensible defaults, so a run with no changes returns a 30 day calendar starting today for London in UTC. | Field | Description | Default | | --- | --- | --- | | Start date | First day, in YYYY-MM-DD. Empty means today. | today | | Number of days | How many days to return, one row each. | 30 | | Include moonrise and moonset | Add rise and set times for the location below. | on | | Latitude | Observer latitude in decimal degrees. | 51.5074 | | Longitude | Observer longitude in decimal degrees. | -0.1278 | | Time zone | IANA name such as UTC, Europe/London, or America/New_York. All dates and times use it. | UTC | ### Example output ```json { "date": "2026-07-29", "weekday": "Wednesday", "phaseName": "Full Moon", "phaseEmoji": "πŸŒ•", "illuminationPercent": 100.0, "moonAgeDays": 15.09, "distanceKm": 399901, "principalPhase": "Full Moon", "principalPhaseTime": "2026-07-29 14:35", "moonrise": "2026-07-29 20:41", "moonset": "2026-07-29 04:52" } ```` ### Accuracy Phase, illumination, distance, and the principal phase times come from the ephem library, the Python binding to the long standing XEphem astronomy engine. Phase times are accurate to within about a minute. Moonrise and moonset use standard atmospheric refraction and are accurate to a minute or two, which is the usual precision for an almanac. ### Notes on time zones The date of a full or new moon can differ by one calendar day depending on the zone you pick, because the exact moment is a single instant worldwide. Set the time zone to your own to see the calendar the way your sky shows it. # Actor input Schema ## `startDate` (type: `string`): First day of the calendar in YYYY-MM-DD. Leave empty to start from today. ## `days` (type: `integer`): How many days to output. One row per day. ## `includeRiseSet` (type: `boolean`): Add moonrise and moonset times for the latitude and longitude below. ## `latitude` (type: `number`): Observer latitude in decimal degrees, used for moonrise and moonset. The default is London. ## `longitude` (type: `number`): Observer longitude in decimal degrees, used for moonrise and moonset. The default is London. ## `timezone` (type: `string`): IANA time zone for all dates and times, for example UTC, Europe/London, or America/New\_York. ## Actor input object example ```json { "startDate": "", "days": 30, "includeRiseSet": true, "latitude": 51.5074, "longitude": -0.1278, "timezone": "UTC" } ``` # Actor output Schema ## `results` (type: `string`): One row per day with moon phase, illumination, and rise and set times. # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("mangudai/moon-phase-lunar-calendar").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`πŸ’Ύ Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // πŸ“š Want to learn more πŸ“–?
