- And don't forget about selectors (classes or what have you, id?)! The previous answers will change the date-attribute of all elements with the specified date-attribute, no matter how punse it sounds)) !!! - Sergey V.

- the only thing that is bad is js changing, but the initial html remains - if this parameter was not reset when rebooting ... - Vasya
- Change the parameter on the server so that when it restarts, it takes the desired value. 2nd option: store the data in localStorage, from where take it to js when loading / reloading the page to the browser. - Visman
