In my humble opinion the best way is to just add a full day in milliseconds  depending on how you factor your code it can mess up if your on the last day of the month   for example Feb 28 or march 31   Here is an example of how i would do it   var current   new Date       Mar 11 2015  current getTime     1426060964567 var followingDay   new Date current getTime     86400000        1 day in ms followingDay toLocaleDateString      imo this insures accuracy  here is another example i Do not like that can work for you but not as clean that dose the above   var today   new Date  12 31 2015    var tomorrow   new Date today   tomorrow setDate today getDate   1   tomorrow toLocaleDateString      imho this      POOP   So some of you have had gripes about my millisecond approach because of day light savings time  So Im going to bash this out  First  Some countries and states do not have Day light savings time  Second Adding exactly 24 hours is a full day  If the date number dose not change once a year but then gets fixed 6 months later i don t see a problem there  But for the purpose of being definite and having to deal with allot the evil Date   i have thought this through and now thoroughly hate Date  So this is my new Approach   var dd   new Date       or any date and time you care about  var dateArray    dd toISOString   split  T   0  split  -   concat  dd toISOString   split  T   1  split              2016    07    04    00    17    58 849Z   at Z    Now for the fun part   var date          day  dateArray 2       month  dateArray 1       year  dateArray 0       hour  dateArray 3       minutes  dateArray 4       seconds dateArray 5  split      0       milliseconds  dateArray 5  split      1  replace  Z          now we have our Official Valid international Date Object clearly written out at Zulu meridian   Now to change the date     dd setDate dd getDate   1      this gives you one full calendar date forward   tomorrow setDate dd getTime     86400000     this gives your 24 hours into the future  do what you want with it
