I am working with an API that requires a certain type of Date format. The date example I am being provided is 10/1/2020 and it converts to 1601528400000. I have never used this type of date before and completely puzzled on what it could be. Does anyone know what type of date format this is?
Example of the URL: https://www.test.org/exports?s_id=-100&g_id=-100&c_id=-100&start_date=1601528400000&end_date=1602478800000

Im consuming a REST api that returns a datetime in the format 2022-09-08T00:21:32.712+03:00 this translates to 08/09/2022 00:21. How do I convert a date value say 08/09/2022 00:21 to the format 2022-09-08T00:21:32.712+03:00 in C#? I have tried below cord without success
string NIRA_CREATEDDATE_FORMATED = NIRA_CREATEDDATE.ToString("yyyy-MM-dd'T'HH:mm:ss.fffffff'Z'");
That is an ISO 8601 format. C# will output it if you use the "o" format.
DateTime.Now.ToString("o")
Note that you'll likely see a higher level of precision than the one you've provided, but that won't typically matter.

Can parse date DateTime.Parse [duplicate]

This line is parsed DateTime.Parse("08/08/2000 00:00:00")
This line isn't parsed DateTime.Parse("08/24/2000 00:00:00")
Question is very simple and stupid, I'm sorry but can't figure out why.
This is likely a localization issue, where it's trying to parse in day/month/year format, and you're assuming it's month/day/year format.

Why is this throwing System.FormatException:String was not recognized as a valid DateTime [duplicate]

Why does this:
Convert.ToDateTime("08/31/2017")
throw an System.FormatException but not this:
Convert.ToDateTime("09/12/2017")
If you need more information please ask and I will update or comment. I have no clue what is causing this issue, so I don't know what details you need.
The default order for this date format on your computers culture is Day/Month/Year, as 31 is not a valid month it fails. If you want this order, you need to provide the format with it:
var x = DateTime.ParseExact("08/31/2017", "MM/dd/yyyy",CultureInfo.InvariantCulture);

I new here, I'm stuck with this problem when a have an array of strings with values of "120612" and "200612".
I need to convert the strings to a date format like this, "Tues 12 June, 2012". How will I do that?
Thanks in advance.
DateTime.ParseExact is probably what you're looking for:
DateTime.ParseExact("200612", "ddMMyy", System.Globalization.CultureInfo.CurrentCulture)
