Key Rules & Conventions
Commas in a Series
Use commas to separate three or more items in a list. Always include a comma before the conjunction (like 'and' or 'or') that connects the last two items (the Oxford comma).
This rule ensures clarity, especially when the last two items might otherwise be misinterpreted as a single unit or when items in the series are long phrases.
Commas in Dates
When a date includes the month, day, and year, place a comma between the day and the year. If the date appears in the middle of a sentence, place another comma after the year. When only the month and year are given, no comma is needed between them.
These commas help readers pause at the correct points, making dates easier to read and understand within sentences, preventing confusion.
