Google’s John Mueller was asked if removing the date from the article would help search rankings.
John Mueller responded, “Even if you post undated content, Google will still keep time.”
Even when you publish something without a date, Google still keeps time.

In 2017, Google also declared that falsifying your date is an old SEO trick.
But at the same time, Google also said do not continue to update the date based on evergreen content, just keep the original date, if you need other places, you can also add the updated date.
