## Description

Working with dates from different cultures can be a nightmare. Are you tracking ancient texts that mix lunar and solar cycles? Do you need to reconcile a modern Western schedule with an Asian festival date? This MCP solves the problem of date ambiguity by providing precise, bidirectional conversions across over fifteen calendar systems.

It doesn't just change numbers; it bridges gaps in timekeeping. By using Unix timestamps as a universal anchor, your AI client can pinpoint exactly what day and era a historical record refers to, regardless of whether that source used the Julian, Hebrew, or Chinese Zodiac calendar. You gain total temporal accuracy.

When you connect this MCP via Vinkius, your agent gains instant access to sophisticated date logic. Need to know the Chinese zodiac animal for a specific year? Want to convert a date from Persian Solar Hijri to a simple Gregorian date, including hours and minutes? This connector handles it all with reliable metadata retrieval. You stop guessing about historical timekeeping and start getting actionable, precise dates.

## Tools

### convert_to_unix
Turns a date given in any supported calendar system into its specific Unix timestamp number.

### expand_unix
Takes one Unix timestamp and outputs the corresponding dates for multiple different calendars you request.

### get_calendar_context
Retrieves specific cultural metadata, like the Zodiac animal or Imperial Era name, associated with a given calendar year.

## Prompt Examples

**Prompt:** 
```
What was the corresponding Gregorian date when Lunar New Year fell on January 23rd in the Chinese calendar?
```

**Response:** 
```
**Conversion Details:**
*   **Input Calendar:** Chinese Lunar
*   **Input Date:** Jan 23 (Year X)
*   **Unix Timestamp:** 1674307200

**Expansion Results:**
| Calendar System | Date Found |
| :--- | :--- |
| Gregorian | January 23, 2023 |
| Persian (Solar Hijri) | Esfand 15, 1401 |
| Hebrew | Nisan 16, 5783 |

This timestamp confirms the date across three major systems.
```

**Prompt:** 
```
What is the Zodiac animal for the year 2024 and what was the ruling Imperial Era in Japan?
```

**Response:** 
```
**Metadata Retrieval:**
*   **Year:** 2024
*   **Zodiac Animal (Chinese):** Dragon 🐉
*   **Japanese Calendar Context:** Reiwa 6 (令和六年)

This tells you the cultural context for that year, which is crucial when cross-referencing records.
```

**Prompt:** 
```
Convert 'October 10th' from the Gregorian calendar to Unix time and also show it in Persian Solar Hijri.
```

**Response:** 
```
**Conversion Result:**
*   **Input Date (Gregorian):** October 10, [Current Year]
*   **Unix Timestamp:** 1696953600

**Expansion View:**
| Calendar System | Date |
| :--- | :--- |
| Gregorian | October 10, [Year] |
| Persian (Solar Hijri) | Aban 20, [Year] |

Your agent now has a reliable reference for two vastly different systems.
```

## Capabilities

### Determine a universal time stamp from any date
You can convert a date given in any supported calendar system (e.g., Chinese, Persian) into its specific Unix timestamp number.

### Map one timestamp to multiple calendars
Takes one universal Unix timestamp and outputs the corresponding dates for several requested calendar systems at once.

### Get cultural context metadata for a year
Retrieves specific cultural metadata, like the Zodiac animal or Imperial Era name, tied to a given calendar year.

## Use Cases

### Reconciling Ancient Texts
A researcher finds an artifact referencing a date in the Japanese Era. Instead of spending days cross-referencing historical almanacs, they ask their agent to use the Calendar Converter MCP and instantly get the modern Gregorian equivalent.

### Planning Global Festivals
A content manager needs to know when a specific Chinese festival falls relative to a Western holiday. They feed the start date into the tool, which uses `expand_unix` to show the overlap and timing across both calendar systems.

### Standardizing Archival Records
An archivist has records spanning centuries using different local dating methods (e.g., Coptic, Julian). They use the MCP to convert every date into a standardized Unix timestamp for database entry and comparison.

### Understanding Historical Cycles
A student needs to know what major historical cycles were active in 100 AD. Using `get_calendar_context`, the agent quickly identifies not just the year, but also the ruling emperor's era name.

## Benefits

- Stop guessing about historical dates. The `convert_to_unix` tool gives you a single, universal timestamp anchor, eliminating ambiguity across any calendar system.
- Get an instant overview of any date using `expand_unix`. You don't have to run separate queries for Gregorian, Persian, and Chinese calendars—it all happens in one call.
- Identify cultural context immediately. Use `get_calendar_context` to find the specific Zodiac animal or Imperial Era name for a year, adding deep detail to your research notes.
- Works with granular precision. It handles time down to the hour, minute, and second, making it reliable for accurate event scheduling across multiple zones.
- Saves hours of manual cross-referencing. Instead of consulting complex historical charts, you simply ask your agent for a conversion, and it delivers the result.

## How It Works

The bottom line is: instead of looking up conversion tables manually, your agent runs one query and gets multiple, cross-referenced dates back instantly.

1. Start by telling your agent which date and calendar system you are working with (e.g., 'January 15, 1920 in the Hebrew calendar').
2. Your AI client sends this data to the MCP, which first converts it into a universal Unix timestamp.
3. Finally, the MCP uses that single timestamp to generate and return the corresponding date details across all the calendars you requested.

## Frequently Asked Questions

**How does the Calendar Converter MCP help me compare dates from Chinese and Western calendars?**
It gives you a single common reference point. Instead of converting manually, your agent uses the tool to map both dates to a universal Unix timestamp, making direct comparison simple and accurate.

**Can I use Calendar Converter for historical records that include zodiac signs?**
Yes. You can use the MCP's context retrieval tools to find metadata like the Chinese Zodiac animal for any given year, giving you cultural detail alongside the date itself.

**What kind of calendars does this Calendar Converter support besides Gregorian?**
It supports over fifteen systems. This includes Persian (Solar Hijri), Japanese Era, Hebrew, Chinese Lunar, and others, ensuring broad compatibility for global projects.

**Is the date conversion accurate down to minutes and seconds?**
Yes. The MCP provides precise timestamping that accounts for hours, minutes, and seconds across all supported calendar systems, which is essential for scheduling or scientific work.

**Does Calendar Converter help me understand historical time periods?**
Absolutely. It retrieves metadata like the Imperial Era name in various cultures, letting you know exactly what political or cultural period a recorded date belongs to.
