If a date consists of multiple parts, e.g. years and month, can you add tooltips for both? At the moment the user is tempted to move the mouse between the parts and the tooltip goes away and does not reappear for the other part
Example question to test: Beamer template with different style options for frames
(I moved the part about adding a tooltip to the view count to Add tool tip for view count because comments/answer made me realise that these are in fact different issues and not both caused by the problem of a missing tooltip aslike I first thought. I thought of moving the part about the date to a separate question and leaving the view count here, but this would have invalidated an existing answer. I'd like to apologise to the users who voted for the view count issue!)
