text: In the geologic time scale, the Northgrippian is the middle of the three ages of the Holocene epoch which lies in the Quaternary period. It was officially ratified by the International Commission on Stratigraphy in July 2018 along with the Greenlandian and the Meghalayan.

The age began 8,236 years prior to the year 2000 (6236 BCE or 3764 HE), near the 8.2 kiloyear event, and goes up to the start of the Meghalayan, which began 4,200 years prior to the year 1950 (2250 BCE or 7750 HE), near the 4.2 kiloyear event.
