Question

In which era, period and epoch do we now live?

Answer 1

Hint: Chronology is the branch of science which helps in arranging the different events in a particular sequence of their occurrence in time. Chronos means “time” and logia means “science”. Chronology is also used in determination of actual temporal science which occurs in the past.

Complete answer:
Periodization is the process of categorizing the events of the past into discrete and quantified blocks of time.
This is a list of historical periods that have been named in various fields of study. Cosmological (time periods in the formation and mass evolution of the cosmos), geological (time periods in the origin and history of the Earth), anthropological, and historical categorization systems are among the most common (time periods in the origin and evolution of human civilization).
An era is a period of time established for the purposes of chronology or historiography, such as regnal eras in the history of a monarchy, calendar eras in the history of a calendar, or geological eras in the history of the Earth. In the International Commission on Stratigraphy's geologic time scale, the Quaternary is the current and most recent of the three Cenozoic Era periods (ICS). From 2.588 0.005 million years ago until the present, it is part of the Neogene Period. The Quaternary Period can be divided into two epochs: the Pleistocene (2.588 million years ago to 11.7 thousand years ago) and the Holocene (11,700 years ago to the present), with the Anthropocene as a third epoch.
An epoch, also known as a reference epoch, is a point in time designated as the start of a calendar era in chronology and periodization. The "epoch" acts as a point of reference for measuring time. A definite, obvious event of change, called an epoch event, is frequently used to determine the epoch instant or date. The geological epoch in which we are living is known as the Holocene. It began approximately 11,650 years ago, followed by the end of the last glacial period, and finally the Holocene glacial retreat.
The Paleozoic, Mesozoic, and Cenozoic eras are the three eras that make up the Phanerozoic Eon. These were given names based on the types of fossils found there. The Cenozoic epoch is the most recent, and its name signifies "new life." This is due to the fossils' resemblance to modern-day animals and flora.
-The era in which we live is the Cenozoic era.
 -The period in which we live is a quaternary period.
 -The epoch in which we live is the Holocene.

Note:
The key issue in chronology is synchronizing occurrences. It is feasible to tie an event to the current time and compare it to other events by synchronizing it. Traditional chronographers like Eusebius, Syncellus, and Scaliger used literary methods of synchronism, but it is also possible to synchronize events using archaeological or astronomical approaches. The Eclipse of Thales, for example.
