Often miss the Xiayuan Festival because it is hard to keep track of lunar dates? This tool automatically calculates the exact time remaining until the 15th day of the 10th lunar month (the traditional Chinese festival known as the Xiayuan Festival). Based on your device's local time, it converts the lunar date in real time and dynamically displays the countdown in days, hours, minutes, and seconds, helping you plan your ceremonies or folk activities in advance.
Q: What exact lunar date is the Xiayuan Festival?
A: It falls on the 15th day of the 10th lunar month. This date is fixed in the lunar calendar and serves as the calculation baseline for this tool.
Q: Does the countdown account for leap months?
A: Yes, the lunar calculation includes leap month rules. For example, the 10th lunar month in 2023 corresponded to November in the Gregorian calendar, while in 2025, a leap 6th month will push the 10th lunar month back. The tool automatically handles these complex calendar conversions.
The countdown's accuracy depends on your device's system time. The results do not include automatic time zone calibration; cross-border use requires manual time difference adjustments. There is no historical date query function; it only displays the countdown from the current time to the next Xiayuan Festival.
The lunar conversion uses astronomical algorithms to calculate synodic months, with an average error of less than 2 minutes. We recommend verifying with the Shixian calendar algorithm: using Beijing Time as the baseline, if the new moon conjunction occurs after 18:00 Beijing Time, the lunar month may be postponed. For example, the Xiayuan Festival in 2024 corresponds to November 15 in the Gregorian calendar, while in 2025, due to a leap 6th month, it will be delayed to December 4.
