480 Years
We are now in the year 5786 after creation. We believe that we can prove by way of the Torah and Talmud, that this number is accurate.
If we were to add up the number of years from Adam to Avraham Avinu, we would find that he was born in the year 1948 after creation. All we need to do is add all the years that so and so begat so and so at a particular age. There were twenty generations and 1948 years.
Yitzchak was born when Avraham was 100 years old. This makes 2048 years. We then add the 400 years from the birth of Isaac until the exodus. This means that the Jews left Egypt 2448 years after creation.
The key number that puts it all together comes from Kings I, verse one. “And it came to pass after 480 years from the exodus from Egypt, Shlomo’s Temple was completed.This takes us to the year 2928 after creation.
The First Temple lasted 410 years, and it was interrupted by the seventy year exile as predicted by the Prophet Jeremiah. The Second Temple lasted 420 years. If we add 410 plus seventy plus 420, This was exactly 900 years, and if we add this to our previous number, we now have 3828, which corresponds to the year 68 of the common era. This was 1958 years ago that our Second Temple was destroyed. If we add 1958 to 3828, we get 5786, the current year.
The key number to this exercise was 480. By adding all of the other known years to the present, we have our proof. This is quite easy and quite amazing!
