以 R 为底：

dates <- seq.Date(from = as.Date("2012-03-01"), length.out = 33, by = "month")
format(dates, "%B %Y")
#>  [1] "March 2012"     "April 2012"     "May 2012"       "June 2012"     
#>  [5] "July 2012"      "August 2012"    "September 2012" "October 2012"  
#>  [9] "November 2012"  "December 2012"  "January 2013"   "February 2013" 
#> [13] "March 2013"     "April 2013"     "May 2013"       "June 2013"     
#> [17] "July 2013"      "August 2013"    "September 2013" "October 2013"  
#> [21] "November 2013"  "December 2013"  "January 2014"   "February 2014" 
#> [25] "March 2014"     "April 2014"     "May 2014"       "June 2014"     
#> [29] "July 2014"      "August 2014"    "September 2014" "October 2014"
