%X This database samples the global continental crust, covering almost the entire history of the Earth. This database collects 2000000 geological age records from 12000 papers and dissertations. This article introduces the compiled raw data, discusses the relationship between dating errors and zircon ages, compares the error levels of different dating instruments, discusses the impact of sampling bias on data analysis, and how to evaluate and minimize this impact. In addition, we also provided an overview of the spatiotemporal distribution of zircon ages worldwide and offered important insights into the potential research value of zircon ages for Earth system science, such as crustal evolution, plate tectonics, and paleoclimate change, as well as their commercial applications in mining and energy exploration. In summary, this data collection provides us with a comprehensive platform for studying deep spatiotemporal zircon geochronology data.  The zircon data compilation includes "database" files and "reference" files. The 'database' file contains approximately 2 million zircon U-Th-Pb dating records, including four isotope ratios (206Pb/238U, 207Pb/235U, 207Pb/206Pb, and 208Pb/232Th) and errors, four corresponding ages and errors, as well as sample information, dating instruments, dating reference materials, host rock lithology, sampling locations, and reference numbers. The 'References' file contains source reference information corresponding to zircon geological age records, including reference number, author, year, and other publication information. For each record in the' Database 'file, its reference can be found in the' References' file by reference number
