OK, found that JSON by definition don't keep the order and thats good when the parsing is made by logical JSON but the system I'm using sees all the JSON as a big string where I can search using regex.

Do the RSS response keeps the same structure always?

The candle lighting item of the JSON looks like this ones:

{
"title": "Candle lighting: 5:31pm",
"hebrew": "הדלקת נרות",
"date": "2018-10-12T17:31:00+03:00",
"category": "candles"
},

But then looks like this:

{
"title": "Candle lighting: 5:31pm",
"category": "candles",
"date": "2018-10-12T17:31:00+03:00",
"hebrew": "הדלקת נרות"
},

1) I cannot parse the data when the order changes everytime, and

2) I'm getting the same candle lighting time when I send b=18 than when I do b=40... !?!
