This article contains heavy spoilers from the Webtoon. The most updated information about Tower of God from the latest chapters can be found here. If you haven't caught up with the Webtoon, read at your own risk.

A timeline of all the events that happened in the webtoon.

The reference timeline is 0, when Bam entered the tower. The time before this will be notated with BB (before Bam) and after will be AB (after Bam).

Time works a little differently in the tower. A 5-6 years time skip in Tower of God is around 1-2 years in real life.

Volume refers to Seasons in the webtoon, to prevent confusion with anime seasons.
