Timezoner

A simple .NET library to provide a consistent list of time zones with Id, Name, and Offset across all platforms.

Why Timezoner?

TimeZoneInfo provides timezones that are available for a particular system, but that list can vary from system to system. This library provides consistent timezone data across Windows, Linux, and macOS platforms.

Installation

dotnet add package Timezoner

Or via Package Manager:

Install-Package Timezoner

Features

✅ Consistent timezone data across all platforms (Windows, Linux, macOS)
✅ Simple and lightweight
✅ Provides timezone Id, Name, and Offset
✅ Built for .NET 10.0
✅ Zero dependencies

Methods

GetTimezones() - Returns a list of all available timezones
GetTimezoneById(string id) - Returns a specific timezone by its Id
GetOffsetAsTimeSpan(string id) - Returns the UTC offset for a timezone by its Id
GetOffsetAsTimeSpan(Timezone zone) - Returns the UTC offset for a timezone object

Usage

// Get all timezones
var timezones = Timezoner.GetTimezones();

// Get a specific timezone by Id
var timezone = Timezoner.GetTimezoneById("Eastern Standard Time");

// Get offset as TimeSpan by Id
var offset = Timezoner.GetOffsetAsTimeSpan("Eastern Standard Time");

// Get offset as TimeSpan from Timezone object
var offset = Timezoner.GetOffsetAsTimeSpan(timezone);

Demo

See Timezoner in action: Live Demo

The demo is a Blazor WebAssembly app, but the library can be used in any .NET application (Console, Web API, Desktop, etc.).

Note: The demo site currently runs on .NET 9 and references Timezoner v1.7.1 until Azure Static Web Apps natively supports .NET 10 in their build pipeline. We prefer to wait for official support rather than implement workarounds.

Requirements

Latest version (2.x): .NET 10.0 or later
Previous versions (1.x): .NET 8.0 and .NET 9.0 (available on NuGet)
