      updateLunarCal: function() {
      		var url1 =  ..... ;
      		var self = this;
      		var nextLoad = this.config.updateInterval;
      		
      		fetch(url1)
      			.then((resp) => resp.json())
      			.then(function(data) {
      				
      				self.lunar = data.LunarDate ;				
      				self.updateDom();
      			})		
      
      			.catch(function(error) {
      				// If there is any error you will catch them here
      			});		
      			
      		setTimeout(function() {
      			self.updateLunarCal();
      		}, 1000);
      
      	},
      
      

      I would like to change as above code of update time from every 1 second to scheduled time. For example: Everyday on 0:00. Please teach me. Thank you

        @kent79 sadly there is no magic here… just grunt work…

        you have to calculate the ms til 0:0:0

        you can use the moment library (yes I know other folks its not the new library)

        // Your moment
        var now = moment();   // now
        
        // Your moment at midnight
        var Midnight = now.clone().startOf('day');  // 00:00:00 today earlier
        
        // Difference in milliseconds
        var milliseconds_passed_already = now.diff(Midnight, 'milliseconds'); // since 00:00:00
        then subtract  
        var milliseconds_til_midnight_tonight = (24*60*60*1000)-milliseconds_passed_already

          May be I explain it clearly.

          I am developing a lunar calender module. As my above coding, it will connect to json server to get the lunar information ervery 1 second.

          I would like to change it to connect server once on Everyday 00:00.

          Since I am a beginner of coding, I don’t know how to do edit it. Please teach me. Thanks

            			if (moment().hours() === 0 && moment().minutes() === 0 && moment().second() === 0) {
            
            				self.updateLunarCal();

            			}
            		}, 100);

              @kent79 well, it will work, BUT you make a check every 100 ms… so LOTS of wasted work… let the system work for you

              fetchIt: function(self){
              		var url1 = "https://abc ....";		
              		
              		fetch(url1)
              			.then((resp) => resp.json())
              			.then(function(data) {
              				// Here you get the data to modify as you please
              				self.lunar = data.LunarDate;							
              				self.updateDom();
              			})
              
              			.catch(function(error) {
              				// If there is any error you will catch them here
              			});	
              },
              
              updateLunarCal: function() {
              
              		let MS_in_day = 24*60*60*1000;
              		let now = moment();
              		let MS_til_midnight = MS_in_day - (now.diff(now.clone().startOf('day'), 'milliseconds')
              
              			
              		// start a one time timer to end of day
              		setTimeout((selft) =>{
              			
              			//in one time timer(at  00:00:00), start interval for next start of day
              			setInterval((selfi)=>{
              				// fetch data, once per day at 00:00:00
              				self.fetchIt(selfi) // use 'this' pointer passed to the interval routine
              			},MS_in_day,
              			  selft)  // pass 'this' pointer passed to us
              
              			// fetch on the 1st start of day, one time
              			self.fecthIt(selft)
              
              		}, MS_til_midnight,
              		   this );  // pass 'this' to the timer routine
              
              		// fetch data now, 1st time
              		this.fetchIt(this);
              }

                Thank you so much for your reply. I got error while running above function. There may be some syntax error. But I can’t fix it. Please help me again. Thanks

                  It seems OK now. I will test it on tonight and will share it to all later. Thank you so much.

                      Would you like to tell me which line need to update since I don’t know how to do? I have tested the above code, no syntax error, but no working while on 00:00. Thanks
