Soenneker.Extensions.DateTime.Quarter

Computes current, previous, and next calendar-quarter boundaries for DateTime, with optional time-zone-aware UTC results.

Installation

dotnet add package Soenneker.Extensions.DateTime.Quarter

Calendar-field boundaries

using Soenneker.Extensions.DateTime.Quarter;

System.DateTime value = new(2026, 8, 29, 16, 42, 30, DateTimeKind.Utc);

System.DateTime start = value.ToStartOfQuarter();       // 2026-07-01 00:00:00
System.DateTime end = value.ToEndOfQuarter();           // last tick of 2026-09-30
System.DateTime nextStart = value.ToStartOfNextQuarter();
System.DateTime previousEnd = value.ToEndOfPreviousQuarter();

Calendar quarters are January–March, April–June, July–September, and October–December.

Method pair	Selected quarter
`ToStartOfQuarter()` / `ToEndOfQuarter()`	Current
`ToStartOfPreviousQuarter()` / `ToEndOfPreviousQuarter()`	Previous
`ToStartOfNextQuarter()` / `ToEndOfNextQuarter()`	Next

Start methods return midnight on the quarter's first date. End methods return one tick before the following quarter. These methods operate on the input calendar fields, preserve Kind, and handle year rollover through DateTime calendar arithmetic.

Time-zone-aware boundaries

TimeZoneInfo eastern = TimeZoneInfo.FindSystemTimeZoneById("America/New_York");
System.DateTime utc = new(2026, 8, 29, 18, 0, 0, DateTimeKind.Utc);

System.DateTime localQuarterStartUtc = utc.ToStartOfTzQuarter(eastern);
System.DateTime localQuarterEndUtc = utc.ToEndOfTzQuarter(eastern);

Time-zone variants are available for the current, previous, and next quarter by adding Tz to the method name, such as ToStartOfPreviousTzQuarter() and ToEndOfNextTzQuarter(). They select the quarter using the input instant's local calendar and return the boundary as a UTC DateTime.

If the input Kind is not Utc, its fields are treated as UTC rather than converted from the machine's local zone. Supply an actual UTC value to avoid ambiguity.

Quarter ends are one tick before the following valid local quarter boundary. If a local quarter begins in a daylight-saving gap, the boundary advances to the first valid local minute; if it is ambiguous, the earlier UTC instant is selected.
