Introduction

Welcome to Wolfgang.Extensions.DateTime!

Overview

Wolfgang.Extensions.DateTime is a .NET library providing extension methods for the System.DateTime type. It adds convenient methods for truncating time precision and navigating to date boundaries (week, month, year).

Key Features

  • TruncateMilliseconds — removes milliseconds, returning a DateTime precise to the second
  • TruncateSeconds — removes seconds and milliseconds, returning a DateTime precise to the minute
  • FirstOfMonth / EndOfMonth — navigates to the first or last instant of the month
  • FirstOfYear / EndOfYear — navigates to the first or last instant of the year
  • FirstOfWeek / EndOfWeek — navigates to week boundaries, with culture-aware or explicit DayOfWeek overloads
  • All methods preserve DateTimeKind (Local, Utc, Unspecified)
