EndOfDayTime.Core

A .NET value type that represents a time of day in the range 00:00–24:00, where 24:00 denotes end-of-day midnight — distinct from 00:00 (start of day).

This concept is defined in ISO 8601 and commonly used in shift scheduling, timesheet applications, broadcasting, and railway timetables.

Installation

dotnet add package EndOfDayTime.Core

Usage

Creating values

var start = new EndOfDayTime(9, 0);    // 09:00
var end   = new EndOfDayTime(24, 0);   // 24:00 — end of day
var eod   = EndOfDayTime.EndOfDay;     // 24:00 — static shorthand

Parsing

var t = EndOfDayTime.Parse("24:00");

if (EndOfDayTime.TryParse("17:30", out var result))
    Console.WriteLine(result); // 17:30

Formatting

var t = new EndOfDayTime(9, 5);
Console.WriteLine(t); // "09:05"

Comparison and arithmetic

var start = new EndOfDayTime(9, 0);
var end   = new EndOfDayTime(24, 0);

TimeSpan duration = end - start;  // 15 hours
bool isLast = end > start;        // true
bool isEod  = end.IsEndOfDay;     // true

JSON serialization (System.Text.Json)

var options = new JsonSerializerOptions();
options.Converters.Add(new EndOfDayTimeJsonConverter());

string json    = JsonSerializer.Serialize(new EndOfDayTime(24, 0), options);  // "24:00"
var    parsed  = JsonSerializer.Deserialize<EndOfDayTime>("\"09:30\"", options);

WPF / WinForms / ASP.NET model binding

The TypeConverter is registered automatically via [TypeConverter] attribute — no configuration needed:


<local:EndOfDayTimeTextBox TimeValue="{Binding ShiftEnd}" />

// ASP.NET Core model binding
public class ShiftDto
{
    public EndOfDayTime End { get; set; }  // "24:00" in JSON binds automatically
}

Notes

24:00 and 00:00 are distinct values — the former is end of day, the latter is start of day.
24:01 and beyond are invalid and will throw ArgumentOutOfRangeException.
The internal representation is a short (total minutes, 0–1440), making it allocation-free.
