The Essential Atlas places the Battle of Yavin, the zero point in the Galactic Standard Calendar per The New Essential Chronology, in 35:3 under the Great ReSynchronization dating system. The Essential Atlas also places the Battle of Selaggis on 43:2:28 and the Battle of Dathomir on 43:3:21. The Essential Guide to Warfare and The Essential Atlas both place the Battle of Dathomir in the year 8 ABY of the Galactic Standard Calendar. The Essential Guide to Warfare also places the Battle of Selaggis in 7 ABY, confirming the placement of the division between each Galactic Standard Calendar year as the third month in the Great ReSynchronization year. Thus, there is a two-month gap between the two dating systems, with the first two months of a GrS year being the last two of the preceding Galactic Standard Calendar year, and there is a total difference of 35 years and 2 months between the two systems.
