It means "a year in our time" rather than a year a very long time ago. It is the system for recording dates used almost everywhere around the world today: it is in common use. CE is an alternative to the AD , system used by Christians but the numbers are the same: this year is CE or equally AD but usually we just say "this year is ". People who are not Christian may not be willing to accept that the Lord of another or any religion should be named when a date is written. For this reason, another way to write a date was needed. When writing about calendars , an era is span of dates, starting from a particular moment in time.
Difference Between BC and BCE

So what is the difference? And which terms should you use in academic writing? The Christian Gregorian calendar is the most widely recognised way of recording years. This is especially important in a historical context. Later, these terms were adopted by historians to distinguish between things that occurred either before BC or after AD the start of the Julian and Gregorian calendars. Keep in mind that the positioning differs depending on the term used, as you might have noticed above.
What Does cal BP Mean?
With some rather heated debate, authors, pundits, scholars, and literary style masters took one side over the other. Decades later, they remain split, but the consensus seems to be that the decision to use one or the other is a personal or organizational preference. The same applies to the use of periods: use or don't use them, based on personal or organizational preference. Both take as their starting point the year when 4th-century Christian scholars believed Jesus Christ was born, designated as AD 1 or 1 CE. The designation of a particular year in either set has identical values.
The Minoan eruption was a major catastrophic volcanic eruption that devastated the Aegean island of Thera now called Santorini in around BCE. Although there are no clear ancient records of the eruption, its plume may have been described in the Egyptian Tempest Stele ,  and the ensuing volcanic winter coincides with a cold wave mentioned in the Chinese Bamboo Annals. Geological evidence shows the Thera volcano erupted numerous times over several hundred thousand years before the Minoan eruption. In a repeating process, the volcano would violently erupt, then eventually collapse into a roughly circular seawater-filled caldera , with numerous small islands forming the circle. The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.
