I have a drupal 7 site that is used for registration for certain events. We are currently using content types to collect the information. What I need is to only allow registered users to post certain content types between a certain set of dates. Certain roles should be able to add/edit at any time.
For example. One of the content types is Grant. But we only accept grants between May 1 and May 31st.
Before May 1st we'd like to have a message that states: Grants are currently not open, please check back May 1st. After May 31st we'd like a message to state: Grants are currently closed for Spring 2018, please try again next year. or something like that.
