Moves a DateTimeOffset to the strictly previous or next occurrence of a weekday, with optional day boundaries and time-zone-aware UTC results.

Installation

dotnet add package Soenneker.Extensions.DateTimeOffsets.DayOfWeeks

using Soenneker.Extensions.DateTimeOffsets.DayOfWeeks;

DateTimeOffset monday = new(2026, 8, 31, 15, 30, 0, TimeSpan.FromHours(-4));

DateTimeOffset previousFriday = monday.ToPreviousDayOfWeek(DayOfWeek.Friday);
DateTimeOffset nextMonday = monday.ToNextDayOfWeek(DayOfWeek.Monday);
DateTimeOffset previousFridayStart = monday.ToStartOfPreviousDayOfWeek(DayOfWeek.Friday);
DateTimeOffset nextFridayEnd = monday.ToEndOfNextDayOfWeek(DayOfWeek.Friday);

Navigation is strict. If the input is already on the requested weekday, the result is seven days away.

ToPreviousDayOfWeek() and ToNextDayOfWeek() preserve the input time and offset. Start/end variants reset the stored clock fields to midnight or one tick before the following date while preserving that offset. These methods do not apply a named time zone's DST rules.

TimeZoneInfo eastern = TimeZoneInfo.FindSystemTimeZoneById("America/New_York");
DateTimeOffset instant = new(2026, 8, 29, 18, 0, 0, TimeSpan.Zero);

DateTimeOffset nextMondayStartUtc =
    instant.ToStartOfNextTzDayOfWeek(DayOfWeek.Monday, eastern);

DateTimeOffset previousFridayEndUtc =
    instant.ToEndOfPreviousTzDayOfWeek(DayOfWeek.Friday, eastern);

The time-zone variants determine the instant's local date, select the strictly previous or next matching weekday, and return the boundary with offset +00:00:

  • ToStartOfPreviousTzDayOfWeek()
  • ToStartOfNextTzDayOfWeek()
  • ToEndOfPreviousTzDayOfWeek()
  • ToEndOfNextTzDayOfWeek()

Starts resolve local midnight using the zone's rules. A midnight in a gap advances to the first valid local time; an ambiguous midnight selects the earlier UTC instant. Ends are one tick before the next valid local day boundary, so 23-hour and 25-hour days are handled without assuming a fixed 24-hour duration.
