    I believe it is still comparing timestamp STRINGS so any timestamp that starts with an number higher than today’s timestamp, even if it’s 50 years ago, will always be greater than today. Suggestion to use a secondary filter, plus: 0, that coerces the timestamp to an integer.


    {% assign today_date = 'now' | date: '%s' % | plus: 0 }
