A collection of instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj61JwpEbGdrcN5Y29ycA" class="cyc_term">Frequency</a>. The members of this collection broadly cover a wide range of frequencies from once a half century to continuously. fact factory classification frequency FactFactoryClassificationFrequency monthly Used to indicate that something happens regularly about once a month Monthly Weekly Used to indicate that something happens regularly on a weekly basis. This differs from PerWeek only in how it is used, and perhaps some would combine them. weekly Daily daily Used to indicate that something happens regularly on an at-least daily basis. once in a lifetime OnceInALifetime Yearly yearly A collection of instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj61JwpEbGdrcN5Y29ycA" class="cyc_term">Frequency</a>.
