How many years between old and new testament

The Old Testament was written over a period of several centuries, from approximately 1200 BCE to 150 BCE. The New Testament, on the other hand, was written in the 1st century CE, with the earliest texts dating back to around 50 CE and the latest texts dating back to around 150 CE.

So, there is a gap of approximately 1,350 to 1,400 years between the Old Testament and the New Testament.

Here's a rough breakdown of the timeline:

It's worth noting that the Old Testament was written in Hebrew, while the New Testament was written in Greek. The Septuagint, a Greek translation of the Hebrew Bible, was produced around 250 BCE, which helped to facilitate the transition from the Old Testament to the New Testament.
