Citation, Documentation of Sources

Q. I have a question about in-text citations. In my reference list I have website sources that do not have a date of creation or a last modified date. How would I cite these references in the text? Would I use n.d. or the access date following the author in the parentheses?

A. Yes, n.d. stands in for a date that can’t be determined. The date of access may be relegated to the reference list, unless it’s relevant to the discussion in the text.
