What is the correct word/term/phrase for "publishing rate"?

If a magazine is published weekly, what is that called? Its "publishing rate" is one week? Its "rate of publishing" is one week? It all sounds wrong.

The term most appropriate for the concept, in my experience, is publishing frequency or just frequency. This is supported by the WikiProject Magazines Infobox template, which uses the term "frequency" to describe how often a magazine is published. It is also used more generally by blogs or any other outlet that produces written media on a certain schedule.

The term "publishing rate", while it certainly doesn't sound particularly bad and is occasionally used to refer to the publishing frequency of magazines or other written media, is typically more associated with scientific fields (see Analysis of the publishing rate [...] of general surgery dissertations) and hence, seems a little formal for describing something like a magazine.

In the context in which your audience are aware of the fact you're discussing a magazine (i.e, you're not talking about the concept but rather how it relates to a certain magazine), however, the preferable choice is likely to just use a term like "daily", "weekly", "monthly", or "yearly" (all of which refer to the periodicity of a publication) - this is easily understood and less formal.

An example of the term publishing rate used in context is this article, which uses the phrase as follows:

Time Inc. cuts magazines' publishing frequency

On the other hand, an example of the terms used to refer to periodicity mentioned previously are the Wikipedia categories for magazines, which follow the format:

Category: [Weekly/Monthly] magazines
