Want to know how long it is until the next White Dew (Bailu) solar term? This tool automatically retrieves the current time, calculates the exact moment the sun reaches a solar longitude of 165° based on astronomical algorithms, and displays a live countdown of the remaining days, hours, minutes, and seconds, helping you track the changing of the seasons.
Q: Does the White Dew solar term fall on the same day every year?
A: No. White Dew usually falls on September 7th or 8th in the Gregorian calendar, but the exact moment is determined by the sun reaching a solar longitude of 165°, which varies slightly each year.
Q: What time zone does this tool use?
A: It uses China Standard Time (UTC+8), which is identical to Beijing Time.
Please ensure your device's system time is accurate to guarantee the precision of the countdown. Results are based on astronomical calculations and may have millisecond-level differences compared to official observatory data. This tool is intended for reference and cultural learning purposes only.
White Dew (Bailu) is the 15th of the 24 traditional Chinese solar terms, marking the beginning of mid-autumn when dew condenses and appears white. This tool uses a solar longitude model for its calculations and is ideal for traditional culture education, daily reminders, and more. For example, the exact time of White Dew in 2024 is September 7 at 23:22:15 (Beijing Time). Visiting the tool at that exact moment will display “0 days 0 hours 0 minutes 0 seconds”.
