 
 <translate> The question Passage: Quaternary (/ kwəˈtɜːrnəri /) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.588 ± 0.005 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.588 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today). The informal term "Late Quaternary" refers to the past 0.5 -- 1.0 million years.

Question: Based on this passage, when did the quaternary period begin and end? <ibo> Ajụjụ: Quaternary (/ kwəˈtɜːrnəri /) bụ oge ugbu a na nke kachasị ọhụrụ n'ime oge atọ nke Cenozoic Era na usoro oge nke International Commission on Stratigraphy (ICS). Ọ na-eso Oge Neogene ma gbasaa site na 2.588 ± 0.005 nde afọ gara aga ruo ugbu a. A na-ekewa oge Quaternary n'ime oge abụọ: Pleistocene (2.588 nde afọ gara aga ruo 11.7 puku afọ gara aga) na Holocene (11.7 puku afọ gara aga ruo taa). Okwu ahụ a na-akpọghị aha ya bụ "Late Quaternary" na-ezo aka n'afọ ndị gara aga dị ka nde afọ ise na ọkara ruo otu nde afọ na ọkara.
