It’s probably just your formatting of the date in the frontmatter. The date value has to be very specifically formatted for Hugo to realize it’s a date and not something else (like a string). What type of frontmatter are you using? If it’s toml, the date needs to be in ISO 8601 full zulu form like 2006-05-27T07:32:00Z If it’s another frontmatter type, I’m not sure, but google probably can help you there.
