In the [[geologic time scale]], the '''Greenlandian''' is the earliest [[age (geology)|age]] or lowest [[stage (stratigraphy)|stage]] of the [[Holocene]] [[Epoch (geology)|epoch]] or [[series (stratigraphy)|series]], part of the [[Quaternary]].<ref name=ics>{{cite web |last1=International Commission on Stratigraphy |title=ICS chart containing the Quaternary and Cambrian GSSPs and new stages (v 2018/07) is now released! |url=http://www.stratigraphy.org/index.php/ics-news-and-meetings/120-ics-chart-containing-the-quaternary-gssps-and-new-stages-v-2018-07-is-now-released |accessdate=15 July 2018}}</ref><ref name="Cohen-etal-2018">{{cite web |last1=Cohen |first1=Kim Mikkel, David A.

The age was officially ratified by the [[International Commission on Stratigraphy]] in July 2018 along with the [[Meghalayan]] and the [[Northgrippian]].<ref name=ics/>
