 Since Chrome 104 newly created cookies or those updated with an expiration date have had that day capped at no more than 400 days in the future, this same limit will now be retroactively applied to cookies already in storage. The expiration dates on these cookies will be capped at no more than 400 days after the first time Chrome 119 or higher starts up and does a one-time database migration. The impact of this change will not be felt by users until at least 400 days after Chrome 119 is released and then only for existing cookies that have not been updated in that period.
