This week I want to write an interactivity，named Day in calendar.
I choose the wiki-What if as we wake up every morning we get to choose a day of our lives to relive.
-You can return to this day by circled on the calendar.
-Every day can freely choose the previous day, the range is this year, for example, today is June 1, then you can choose any relive from January 1 to June 1.
-After the selected day passes, the time still passes normally. For example, select February 1st, and then it will be 2nd.
