In my answer on the question Scripting Games 2007 Advanced PowerShell Event 3 and 4 , I used a formula the get the Chinese Year.
But to get from a date to a Year would take much more work, as the Chinese Year do not start and end on the same day. (so the scripting guys did say we could ignore it ), And today is New Year ( See second example)
But there is another very Powerfulway using .NET is this Includes a Chinese Calendar that does all the work for us :
PoSH> $cc = new-Object System.Globalization.ChineseLunisolarCalendar PoSH> $cc MinSupportedDateTime : 2/19/1901 12:00:00 AM MaxSupportedDateTime : 1/28/2101 11:59:59 PM Eras : {1} AlgorithmType : LunisolarCalendar TwoDigitYearMax : 2029 IsReadOnly : False PoSH> $cc.GetYear("02/18/2007") 2007 PoSH> $cc.GetYear("02/17/2007") 2006 PoSH>
So this new version is done also in a few lines is very simple and does not need a lot of Math
function get-ChineseYear ([datetime]$date){
$cc =new-Object System.Globalization.ChineseLunisolarCalendar
$SexanageryYear = $cc.GetSexagenaryYear($date)
$TerrestrialBranch = $cc.GetTerrestrialBranch($SexanageryYear)
$cYear = "rat,ox,tiger,hare,dragon,snake,horse,sheep,monkey,fowl,dog,pig".split(',')
$cYear[$TerrestrialBranch -1 ]
}
$cc =new-Object System.Globalization.ChineseLunisolarCalendar
$SexanageryYear = $cc.GetSexagenaryYear($date)
$TerrestrialBranch = $cc.GetTerrestrialBranch($SexanageryYear)
$cYear = "rat,ox,tiger,hare,dragon,snake,horse,sheep,monkey,fowl,dog,pig".split(',')
$cYear[$TerrestrialBranch -1 ]
}
This Object looks a lot like the normal DateTime Object , but has some extra functionality it has the following Methods adn Properties:,
PoSH> $cc | Get-Member TypeName: System.Globalization.ChineseLunisolarCalendar Name MemberType Definition ---- ---------- ---------- AddDays Method System.DateTime AddDays(DateTime time, Int32 days) AddHours Method System.DateTime AddHours(DateTime time, Int32 hours) AddMilliseconds Method System.DateTime AddMilliseconds(DateTime time, Double milliseconds) AddMinutes Method System.DateTime AddMinutes(DateTime time, Int32 minutes) AddMonths Method System.DateTime AddMonths(DateTime time, Int32 months) AddSeconds Method System.DateTime AddSeconds(DateTime time, Int32 seconds) AddWeeks Method System.DateTime AddWeeks(DateTime time, Int32 weeks) AddYears Method System.DateTime AddYears(DateTime time, Int32 years) Clone Method System.Object Clone() Equals Method System.Boolean Equals(Object obj) GetCelestialStem Method System.Int32 GetCelestialStem(Int32 sexagenaryYear) GetDayOfMonth Method System.Int32 GetDayOfMonth(DateTime time) GetDayOfWeek Method System.DayOfWeek GetDayOfWeek(DateTime time) GetDayOfYear Method System.Int32 GetDayOfYear(DateTime time) GetDaysInMonth Method System.Int32 GetDaysInMonth(Int32 year, Int32 month, Int32 era), System.Int32 Ge...

With them I made the Following 2 Functions Get-ChineseYear and get-ChineseDate , the latter one giving much more information about the date
PoSH> get-ChineseYear 02/18/2007 pig PoSH> get-ChineseYear 02/17/2007 dog PoSH> get-ChineseDate 02/18/2007 Date : 02/18/2007 00:00:00 Chinese Date : Day : 1 Month : 1 Year : 2007 Leap Day : False Leap Month : False Year Info : This Year starts on : 2/18/2007 This Year Ends on : 2/6/2008 This Year has 12 Months Sexanagery Year : 24 CelestialStem : 4 TerrestrialBranch = 12 This is the Year of the pig PoSH> get-ChineseDate 02/17/2007 Date : 02/17/2007 00:00:00 Chinese Date : Day : 30 Month : 13 Year : 2006 Leap Day : False Leap Month : False Year Info : This Year starts on : 1/29/2006 This Year Ends on : 2/17/2007 This Year has 13 Months This Year has a leap Month The Leap Month of this year is Month 8 Sexanagery Year : 23 CelestialStem : 3 TerrestrialBranch = 11 This is the Year of the dog PoSH>
You can see that with PowerShell at hand your an complete expert on the Chinese Calendar ;-)
Both Scripts :
function get-ChineseYear ([datetime]$date){ $cc =new-Object System.Globalization.ChineseLunisolarCalendar $SexanageryYear = $cc.GetSexagenaryYear($date) $TerrestrialBranch = $cc.GetTerrestrialBranch($SexanageryYear) $cYear = "rat,ox,tiger,hare,dragon,snake,horse,sheep,monkey,fowl,dog,pig".split(',') $cYear[$TerrestrialBranch -1 ] } function get-ChineseDate ([datetime]$date){ $cc =new-Object System.Globalization.ChineseLunisolarCalendar $SexanageryYear = $cc.GetSexagenaryYear($date) $CelestialStem = $cc.GetCelestialStem($SexanageryYear) $TerrestrialBranch = $cc.GetTerrestrialBranch($SexanageryYear) $cYear = "rat,ox,tiger,hare,dragon,snake,horse,sheep,monkey,fowl,dog,pig".split(',') $BranchName = $cYear[$TerrestrialBranch -1 ] $Year = $cc.GetYear($date) $Day = $cc.GetDayOfMonth($date) $Month = $cc.GetMonth($date) "Date : $date `n" "Chinese Date :`n" " Day : $Day " " Month : $Month " " Year : $Year `n" " Leap Day : $($cc.IsLeapDay($year,$Month,$day,1))" " Leap Month : $($cc.IsLeapMonth($year,$Month,1))" "`nYear Info :`n" $firstday = $date.AddDays( - $cc.GetDayOfYear($date) + 1) $Lastday = $firstday.AddDays($cc.GetDaysInYear($year,1) - 1).ToShortDateString() " This Year starts on : $($FirstDay.ToShortDateString())" " This Year Ends on : $Lastday" " This Year has $($cc.GetMonthsInYear($year,1)) Months" if ($cc.GetLeapMonth($year ,1) -ne 0 ){" This Year has a leap Month`n The Leap Month of this year is Month $($cc.GetLeapMonth($year ,1))"} "`n Sexanagery Year : $SexanageryYear " " CelestialStem : $CelestialStem" " TerrestrialBranch = $TerrestrialBranch `n" " This is the Year of the $BranchName" }
Welcome in the year of the Pig
Enjoy,
