# Takes one parameter -- the start month -- which allows for numbering folders based on fiscal years rather than calendar years.  The default is 1 for January.

Param(
    [int]$startMonth = 1
)

$dateinfo = new-object system.globalization.datetimeformatinfo

$months = $dateinfo.MonthGenitiveNames

for($i=0; $i -lt ($startMonth-1); $i++) {
    $monthValue = $months[0]
    $months = $months[1..11]
    $months = $months + $monthValue
}

for($i=0;$i -lt 12;$i++) {
    $folderName = ($i+1).ToString("00") + "-" + $months[$i]
    md -Name $folderName
#    write-host $folderName
}
