Q. When should I include day and month in my citation and reference?
Newsletters, magazines, and newspapers are often published on a monthly, weekly, or daily basis. If a publication is put out on a monthly basis, then the month should be included with the year. in your reference. If a publication is released daily, the day should also be included in your reference. Alternatively, if a season like Spring is listed, or two seasons (i.e., Spring/Summer), this should be listed in your reference.
Your in-text citation only requires the year of publication.
