    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

          				self.updateLunarCal();

          			}
          		}, 100);
          

          I have revised as above code. Is it achieve my goal?

            @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
