Display event from json

Hi
If I understood your problem correctly
You have to set date which comes in in below JSON.
[{“name”:“firstlesson”, “start_time”:2019-09-22 17:13:02}]

I think you can take reference from below solutions

Your JSON is
[{“name”:“firstlesson”, “start_time”:2019-09-22 17:13:02}]

1.You can save this start_time in mydate variable
2. and once it will update it can set on calender.

Give a try.

Thanks
