The traditional East Asian calendars divide a year into 24 solar terms (節氣). Jīngzhé (pīnyīn) or Keichitsu (rōmaji) (Traditional Chinese: 驚蟄; Simplified Chinese: 惊蛰; Japanese: 啓蟄; Korean: 경칩; Vietnamese: Kinh trập; literally: "awakening of insects") is the 3rd solar term. It begins when the Sun reaches the celestial longitude of 345° and ends when it reaches the longitude of 360°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 345°. In the Gregorian calendar, it usually begins around March 5 and ends around March 20.

The word 驚蟄 has the meaning of awakening of hibernated insects. is startling, and is hibernated (insects). The traditional Chinese farming culture said that during Jingzhe, thunderstorms will wake up the hibernated insects, which also means the weather is getting warm.
