PH probe calibration

Was wondeing how often I should calibrate my PH probe?
I think this is a personal preference.
I never calibrate mine, but I know people that do that every week.
What I do often though is place the probe in vinegar to kill any bacteria/algae growth that covers the glass bulb.
They can cause a small drift in readings.
