Jingzhe

Jīngzhé (simplified Chinese: 惊蛰; traditional Chinese: 驚蛰) is the 3rd of the 24 solar terms (節氣) in the traditional Chinese calendars. It begins when the Sun reaches the celestial longitude of 345° and ends when it reaches the longitude of 360°. More often, it refers to the day when the Sun is exactly at a celestial longitude of 345°. In the Gregorian calendar, it usually begins around March 5 and ends around March 20.

The word 驚蟄 means the awakening of hibernating insects. 驚 is to startle and 蟄 means hibernating insects. Traditional Chinese folklore says that during Jingzhe, thunderstorms will wake up the hibernating insects, which implies that the weather is getting warmer.
