Contamination from outside, or the loss of isotopes at any time from the rock's original formation, would change the result.
It is therefore essential to have as much information as possible about the material being dated and to check for possible signs of alteration.
As with the Calendar Wikia, the text of Wikipedia is available under Creative Commons License. The Holocene calendar, Human Era count or Jōmon Era count (Japan) uses a dating system similar to astronomical year numbering but adds 10,000, placing a year 0 at the start of the Jōmon Era (JE), the Human Era (HE, the beginning of human civilization) and the aproximate beginning of the Holocene Epoch (HE) for easier geological, archaeological and, especially for Japanese regnal years, historical dating.

 Cesare Emiliani’s proposal for a calendar reform sought to solve a number of problems with the current Gregorian Calendar, which currently serves as the commonly accepted world calendar.
The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.
Anything which changes the relative amounts of the two isotopes (original and daughter) must be noted, and avoided if possible.

Measurements should be taken on samples from different parts of the rock body.
This helps to counter the effects of heating and squeezing, which a rock may experience in its long history.
