Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: relative dating and absolute dating.

Opinion differs on the diagnostic value of this procedure for differentiating between historical and recent skeletonized human remains. Design: Chemiluminescence CL was tested in randomized, blind experiments on pulverized bone samples with known postmortem intervals from four different periods 1st-3rd century, , , In addition to determining the sensitivity and specificity of the CL-analysis, likelihood ratios and predictive values were calculated.
