When you use Harvard referencing
Harvard is the author-date style used across most UK, Irish, Australian and South African universities. If your lecturer says reference in Harvard, they mean citations like (Smith, 2023) in the text and a full alphabetical reference list at the end.
Here is the honest thing about Harvard that most students find out the hard way: there is no single official Harvard manual. Unlike APA or MLA, no association owns it, so every university publishes its own variant. The differences are small, italics here, a comma there, but markers do notice. The format this generator produces follows the most common modern convention, the one popularized by the Cite Them Right guide, which is what a large share of UK universities point students to.
That means the workflow is: generate the reference here, then skim your own university's style page once to see if it wants anything unusual, like bold volume numbers or no parentheses around the year. Ninety percent of the time the output matches as is.

In-text citations
Two authors: (Smith and Lee, 2023). Three authors: (Smith, Lee and Chen, 2023). Four or more: (Smith et al., 2023). Same author, same year, two works: label them 2023a and 2023b in both the text and the reference list.
