Wondering how long until spring arrives? The Start of Spring (Lichun) countdown tool automatically uses astronomical algorithms to calculate the exact time remaining until the next Lichun solar term in real-time, including days, hours, minutes, and seconds. Lichun is the first of the 24 traditional Chinese solar terms, marking the beginning of spring. Its date on the Gregorian calendar usually fluctuates between February 3rd and 5th.
Q: Is the date of Lichun fixed every year?
A: No, it is not fixed. The date of Lichun on the Gregorian calendar is usually February 3rd, 4th, or 5th, depending on the exact moment the Sun reaches the celestial longitude of 315°.
Q: Do I need to enter my location or time zone?
A: No. The tool defaults to using your system's local time for calculations, which works for the vast majority of users.
Please ensure your device time is set accurately to get the most precise countdown. The results are for reference only; the exact solar term times are subject to official releases by the National Time Service Center. This tool does not collect any user data, so you can use it with confidence.
The calculation of Lichun is based on the solar celestial longitude, accurate to the hour, minute, and second. For example, Lichun in 2024 is on February 4 at 16:26:53, and in 2025, it is on February 3 at 22:10:13. If you need to programmatically obtain the Lichun time, you can refer to the national standard "Calculation Algorithm of Lunar Calendar Solar Terms" (GB/T 33661-2017).
