I think a good option would be,

when the web page opens first store the date to local storage, when its open normally check the date in local storage every minute and then validate it and take action.

setIterval sounds like a very bad way of doing it here...

On start up get the data,

save the date using localStorage.setItem("date", datevariblename);

on load or everytime you in the set interval use localStorage.getItem("date") to get the date value

Then do what every comparsion is required between current date and save date

setTimeout is pretty darn precise for longer periods. I had the requirement myself some time ago, so I did some testing across browsers. Even if you have a timeout that lasts 24 hours for instance, the callback gets fired precisely (variance is in the area of miliseconds).

setTimeout (or more exactly, the implementation) does not use a "countdown". It will ask the operating system to give it a SIGnal when the time period is over.
