Frequently Asked Questions (FAQ)

Does the Rain Water solar term fall on the same day every year?
No. The exact date is determined by the sun's longitude. On the Gregorian calendar, it typically fluctuates between February 18th and 20th each year.

How is the countdown accuracy guaranteed?
The tool calculates based on server time and updates automatically every second. If your device's time is out of sync, it may affect display accuracy. We recommend refreshing the page to fetch the latest data.

Important Notes

This tool is for reference only. Actual agricultural planning should account for local climate conditions. The countdown relies on network time synchronization; in extreme cases, refresh the page to reset it. Reminder features are not supported, so please record important schedules manually.

Technical Notes & Usage Suggestions

The Rain Water solar term corresponds to a solar longitude of 330°, calculated using standard astronomical algorithms. A typical output example: If Rain Water in 2024 is on February 19th, the countdown will display "8 days, 15 hours, 30 minutes, and 25 seconds remaining." Agricultural users are advised to combine this with local phenological observations to determine the best planting times, rather than relying solely on solar term dates.
