Here is a code snippet with standard DateTime formats
DateTime today = DateTime.Now; Console.WriteLine($"D: {today.ToString("D")}");
Console.WriteLine($"d: {today.ToString("d")}");
Console.WriteLine($"F: {today.ToString("F")}");
Console.WriteLine($"f: {today:f}");
Console.WriteLine($"G: {today:G}");
Console.WriteLine($"g: {today:g}");
Console.WriteLine($"M: {today:M}");
Console.WriteLine($"O: {today:O}");
Console.WriteLine($"o: {today:o}");
Console.WriteLine($"R: {today:R}");
Console.WriteLine($"s: {today:s}");
Console.WriteLine($"T: {today:T}");
Console.WriteLine($"t: {today:t}");
Console.WriteLine($"U: {today:U}");
Console.WriteLine($"u: {today:u}");
