Is month of ACS administration available?

The 5-year ACS provides year of survey administration, but I cannot find the month of administration. Any help greatly appreciated! Bob

The month of ACS survey administration is not available. We’ve been told that the Census Bureau does not release the survey month in the public use files due to concerns that people will misuse the information statistically (e.g., to try to get estimates of the population for a particular month, which shouldn’t be done).
