Single-year estimates from the American Community Survey (ACS) are "period" estimates derived from a data sample collected over a period of time, as opposed to "point-in-time" estimates such as those from past decennial censuses. ACS single-year estimates include data collected over a 12-month period; explicitly the calendar year (e.g., the 2015 ACS covers the period from January 2015 through December 2015).
Please see the ACS handbook (Section 3, "Understanding and Using ACS Single-Year and Multiyear Estimates" p. 13) for a comprehensive set of details and clarifications: https://www.census.gov/content/dam/Census/library/publications/2018/acs/acs_general_handbook_2018.pdf"
