610 CE is after Christ, as CE stands for Common Era, which is equivalent to AD (Anno Domini). The CE/AD system measures time from the traditionally calculated birth year of Jesus Christ.
Here's why:
CE is a secular equivalent to AD: CE stands for "Common Era" and is used as a secular alternative to AD, which stands for "Anno Domini" (Latin for "in the year of the Lord").
Both systems start from the same point: Both AD and CE use the estimated birth year of Jesus Christ as the starting point (Year 1).
610 CE indicates a year after the starting point: Therefore, 610 CE refers to a year that occurred 610 years after that starting point, placing it well after the time of Christ's birth.
For instance, 1 CE is the same year as AD 1. Events in 610 CE fall within the time period measured by both AD and CE.
