| ## What is DateTimeExtensions? | ||
|
|
||
| This project is a merge of several common DateTime operations in the form of | ||
| extensions to System.DateTime and System.DateTimeOffset, including natural date difference text (precise and human rounded), | ||
| holidays and working days calculations on several culture locales. | ||
| 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. | ||
|
|
||
| Feedback will be much appreciated. | ||
| You can check out a sample (WIP) project online on [http://datetimeextensions.azurewebsites.net/](http://datetimeextensions.azurewebsites.net/) | ||
| ## Key Features | ||
|
|
||
| ## Major Features | ||
| 1. **Working Days Calculations**: Easily add or subtract working days, taking into account regional holidays. | ||
| 2. **Holiday Support**: Includes holiday definitions for multiple cultures and regions. | ||
| 3. **Natural Language Date Differences**: Get the difference between dates in human-readable format. | ||
| 4. **Time of Day Operations**: Simplify time-based comparisons and checks. | ||
| 5. **Calendar Export**: Export holidays to common calendar formats. | ||
| 6. **SourceLink Support**: Enables debugging into the source code. | ||
|
|
||
| The following major features are currently implemented: | ||
| ## Installation | ||
|
|
||
| + Add or subtract Working days using locale holidays | ||
| + Support for Regional holidays (limited locales) | ||
| + Export Holidays to calendar format | ||
| + Dates Difference in Natural Time (localized) | ||
| + Time of day | ||
| + General "goto" dates | ||
| + Supports SourceLink for debugging | ||
| + Extensions to both DateTime and DateTimeOffset (the Date portion) | ||
| Install DateTimeExtensions via NuGet: | ||
|
|
||
| ``` | ||
| Install-Package DateTimeExtensions | ||
| ``` | ||
|
|
||
| ### Working Days Calculations | ||
| ## Quick Start | ||
|
|
||
| These extensions for System.DateTime adds methods to make calculations based on working days. | ||
| A working day is defined in `IWorkingDayCultureInfo` in two ways: | ||
| Here are some examples of what you can do with DateTimeExtensions: | ||
|
|
||
| ````csharp | ||
| IsWorkingDay(DayOfWeek dayOfWeek) | ||
| IsWorkingDay(DateTime date) | ||
| ```` | ||
| The first defines which day of the week is a working day (by default, working days are all | ||
| week days except weekends). The last does the same as the first, but it's also able to check | ||
| for any holiday. By default, no holidays are defined, unless there is a `IWorkingDayCultureInfo` | ||
| implemented for the current thread `CultureInfo`. | ||
| ```csharp | ||
| using DateTimeExtensions; | ||
|
|
||
| Available CultureInfo implementations: | ||
| // Add 5 working days to a date | ||
| DateTime futureDate = DateTime.Now.AddWorkingDays(5); | ||
|
|
||
| | Culture | Culture | | ||
| | :-------: | :-------: | | ||
| | pt-PT | da-DK | | ||
| | pt-BR | fi-FI | | ||
| | en-US | is-IS | | ||
| | en-GB | nb-NO | | ||
| | fr-FR | nl-NL | | ||
| | de-DE | sv-SE | | ||
| | es-ES | es-AR | | ||
| | es-MX | en-AU | | ||
| | en-ZA | fr-CA (en-CA)| | ||
| | ar-SA | it-IT | | ||
| | en-NZ | en-GD<br>(gd-GD, not really sure about this locale) | ||
| | en-IE | sl-SL | | ||
| | kr-KR | zh-CN | | ||
| | pl-PL | vi-VN | | ||
| | es-CO | ro-RO | | ||
| // 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)); | ||
|
|
||
| If your culture is not listed here you can contribute it!!! | ||
| // Check if a time is between two other times | ||
| bool isBetween = DateTime.Now.IsBetween(new Time("09:00"), new Time("17:00")); | ||
| ``` | ||
|
|
||
| Fork me, implement it and send me the pull request, or just create an issue on the project github site. | ||
| ## Supported Cultures | ||
|
|
||
| DateTimeExtensions supports working day and holiday calculations for many cultures, including: | ||
|
|
||
| ### Export Holidays to calendar format | ||
| - 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! | ||
|
|
||
| Don't see your culture? Contributions are welcome! | ||
|
|
||
| This feature allows you to export the holidays from a `DateTimeCultureInfo` (see above) | ||
| and export it to Microsoft Office Outlook. | ||
| The `IExportHolidaysFormat` interface exposes one simple method for it: | ||
| ````csharp | ||
| void Export(DateTimeCultureInfo dateTimeCultureInfo, int year, TextWriter writer) | ||
| ```` | ||
| Example: | ||
| ````csharp | ||
| var exporter = ExportHolidayFormatLocator.LocateByType(ExportType.OfficeHolidays); | ||
| exporter.Export(new WorkingDayCultureInfo("pt-PT"), 2012, textwriter); | ||
| ```` | ||
|
|
||
| ### Dates Diff in Natural Time | ||
|
|
||
| These extensions can compare two dates in natural language based on the current locale on | ||
| current thread `CultureInfo`. | ||
| There are 2 API points for them: | ||
| ````csharp | ||
| fromDate.ToNaturalText(toTime, bool round = true) | ||
| fromDate.ToExactNaturalText(toTime) | ||
| ```` | ||
|
|
||
| The first will return the most valuable time component with value > 0. The round flag will | ||
| try to round the most significant time component based on the next least significant. | ||
| Also, the round flag will round minutes and seconds to quarters after the first one. | ||
| ## Advanced Features | ||
|
|
||
| Available CultureInfo implementations: | ||
| ### Exporting Holidays | ||
|
|
||
| | Culture | | ||
| | ------- | | ||
| | pt-PT | | ||
| | pt-BR | | ||
| | en-US | | ||
| | en-GB | | ||
| | fr-FR | | ||
| | de-DE | | ||
| | es-ES | | ||
| | nl-NL | | ||
| | nl-BE | | ||
| | kr-KR | | ||
| | pl-PL | | ||
| | ro-RO | | ||
| You can export holidays to various calendar formats: | ||
|
|
||
| ### Time of Day | ||
|
|
||
| These extensions allow easy parsing of time expressions and add the ability to check if a DateTime instance is after, | ||
| before or inside a period. | ||
| ````csharp | ||
| bool IsBetween(this DateTime dateTime, Time startTime, Time endTime) | ||
| bool IsBefore(this DateTime dateTime, Time time) | ||
| bool IsAfter(this DateTime dateTime, Time time) | ||
| ```` | ||
|
|
||
| ### Other Extensions: | ||
| ```csharp | ||
| var exporter = ExportHolidayFormatLocator.LocateByType(ExportType.OfficeHolidays); | ||
| exporter.Export(new WorkingDayCultureInfo("en-US"), 2024, textWriter); | ||
| ``` | ||
|
|
||
| ````csharp | ||
| fromDate.FirstDayOfTheMonth() | ||
| fromDate.LastDayOfTheMonth() | ||
| fromDate.LastDayOfWeek(DayOfWeek) | ||
| fromDate.NextDayOfWeek(DayOfWeek) | ||
| fromDate.LastDayOfWeekOfTheMonth(DayOfWeek) | ||
| fromDate.FirstDayOfWeekOfTheMonth(DayOfWeek) | ||
| fromDate.GetDiff(DateTime toDate) | ||
| ```` | ||
| ### Custom Working Day Definitions | ||
|
|
||
| ### SourceLink | ||
| Implement `IWorkingDayCultureInfo` to define custom working day rules for your specific needs. | ||
|
|
||
| This library supports SourceLink. Just make sure you have a compatible Visual Studio version and | ||
| the Just My Code is disabled on Debugging options. | ||
