The long-term stability of an oscillator, the degree of uniformity of frequency over time, when the frequency is measured under identical environmental conditions, such as supply voltage, load, and temperature. Long-term frequency changes are caused by changes in the oscillator elements that determine frequency, such as crystal drift, inductance c...

or Long Term Drift is the amount of change of a measured reading at exactly the same pressure and ambient conditions over a given period of time which is typically quoted as an annual figure.
