This is how you can proceed: <script type=”text/javascript”> var timeleft = 30; var downloadTimer = setInterval(function(){ timeleft–; document.getElementById(“countdowntimer”).textContent = “:” + ((timeleft >= 10) ? timeleft : (“0” + timeleft)); if(timeleft <= 0){ clearInterval(downloadTimer); window.location.replace(“next_slide.html”); } },1000); </script> 0 solved Double digit 30 seconds countdown
You can just do: $diff = date_create()->diff(new DateTime(“first day of January “.date(“Y”))); $hours = $diff->format(“%a”)*24 + $diff->h; As requested here’s a way to handle daylight savings: $transitions = (new DateTimeZone(date_default_timezone_get()))->getTransitions(); $thisYearsTransitions = array_values(array_filter($transitions, function ($v) { return substr($v[“time”],0,strlen(date(“Y”))) == date(“Y”); })); if (count($thisYearsTransitions) == 2 && date_create($thisYearsTransitions[0]) < date_create() && count($thisYearsTransitions)>0 && date_create($thisYearsTransitions[1]) > date_create()) … Read more

First define the end case, in this case when n=0. Update the innerHTML and quit (don’t return anything). ELSE return the … Read more
If you want to use only javascript, without any server-side language you could store the time that is left in the localStorage variable, because after you exit the website/browser it will stay the same; Example: function countdown() { time = parseInt(localStorage.time); //All variables in localstorage are strings //Resets timer if cannot parse the localStorage.time variable … Read more
