Keichitsu (啓蟄) is the third of 24 solar terms in the traditional East Asian calendars and is called Jingzhé (驚蟄) in chinese, 경칩 in Korean and Kinh trập  in Vietnamese.

In the Gregorian calendar, it is between around the 5th of March and the 20th of March.

The literal meaning of Keichitsu is awakening of hibernated insects. All the insects and animals started coming out of the underground. Plants are also shooting up baby leaves. 

Apart from now, the weather is becoming mild and warm. It is the beginning of the spring.
