Below are two timelines. The first displays the history of the Age of the Valar and of the Pillars of Light and ends with the creation of the Two Trees.
The second is a timeline of the Valinorean Years, the Years of the Two Trees, the First Count of Time. It ends with Coming of the Sun and Moon, the New count of Time, and the Age of the Two Trees and of the Stars is over.
Each year of the Valar, and likewise of the Two Trees, is about nine to ten Years of the Sun and Moon which came afterwards. Therefore ten Years of the Valar equals, roughly, ninety to a hundred Years of the Sun.
