DateTimeExtensions is a powerful C# library that extends the functionality of System.DateTime
and System.DateTimeOffset
. It provides a set of useful methods for working with dates and times, making your code more expressive and easier to read.
- Working Days Calculations: Easily add or subtract working days, taking into account regional holidays.
- Holiday Support: Includes holiday definitions for multiple cultures and regions.
- Natural Language Date Differences: Get the difference between dates in human-readable format.
- Time of Day Operations: Simplify time-based comparisons and checks.
- Calendar Export: Export holidays to common calendar formats.
- SourceLink Support: Enables debugging into the source code.
Install DateTimeExtensions via NuGet:
Install-Package DateTimeExtensions
Here are some examples of what you can do with DateTimeExtensions:
using DateTimeExtensions;
// Add 5 working days to a date
DateTime futureDate = DateTime.Now.AddWorkingDays(5);
// Check if a date is a working day
bool isWorkingDay = DateTime.Now.IsWorkingDay();
// Get the difference between dates in natural language
string dateDiff = DateTime.Now.ToNaturalText(DateTime.Now.AddDays(45));
// Check if a time is between two other times
bool isBetween = DateTime.Now.IsBetween(new Time("09:00"), new Time("17:00"));
DateTimeExtensions supports working day and holiday calculations for many cultures, including:
- United States (en-US)
- United Kingdom (en-GB)
- France (fr-FR)
- Germany (de-DE)
- Spain (es-ES)
- Brazil (pt-BR)
- Portugal (pt-PT)
- and many more!

You can export holidays to various calendar formats:
var exporter = ExportHolidayFormatLocator.LocateByType(ExportType.OfficeHolidays);
exporter.Export(new WorkingDayCultureInfo("en-US"), 2024, textWriter);
Implement IWorkingDayCultureInfo
to define custom working day rules for your specific needs.
