How this service works
Lunar (農曆) date converter: Gregorian ↔ Chinese lunar date (incl. leap months) with 干支 year and zodiac; e.g. find the solar date of 中秋 (8/15). Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
A JSON object containing the converted date in both Gregorian and Chinese lunar formats, the 干支 (sexagenary) year name, Chinese zodiac animal, leap month status, and payment metadata including whether the free tier was used or a $0.001 USDC charge was made.
Example use cases
Find Mid-Autumn Festival solar date
“When does Mid-Autumn Festival fall in 2026? It's the 15th day of the 8th lunar month — give me the Gregorian calendar date.”
Convert birthday to lunar date
“My birthday is March 22, 2025 — what is my Chinese lunar calendar date, including the 干支 year and zodiac sign?”
Leap month lunar conversion
“Convert the 1st day of the leap 6th lunar month in 2025 to its Gregorian date — make sure to treat it as a leap month.”
Technical details
Endpoint
GEThttps://tools.moneytools.dev/v1/lunar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative Gregorian ↔ Chinese lunar calendar conversion with full support for leap months (閏月), 干支 year names, and zodiac signs. It is especially suited for finding exact solar dates of traditional Chinese holidays like 中秋節 or 春節, or annotating dates with Chinese calendar metadata. Prefer this over generic date libraries that lack leap month handling or 干支 support.
Side effects
- Invalid date format returns an error (date must be YYYY-MM-DD)
- Lunar date out of supported range returns an error
- Leap month flag set for a non-leap month returns an error
- Missing required parameters (no date and no lunar year/month/day combo) defaults to today in Taipei timezone
- Free tier exhausted (10/day) requires x402 payment or API key; without payment returns HTTP 402
