date

问题 It's possible to do this to get the localized full month name using native javascript. var objDate = new Date("10/11/2009"), locale = "en-us", month = objDate.toLocaleString(locale, { month: "long" }); But this only gets the month number for a given date. I'd simply like to get the month name corresponding to a month number. For example, if I do getMonth(2) it would return February . How can I implement getMonth using native javascript(no libraries like moment )? 回答1: You are already close:

问题 Crime analysis data in R: Let's say I have a very large dataset with millions of columns. One of the column has Dates such as "3/28/2020" (mm/dd/YYYY) format. For my analysis, I need a format (dd/mm/YYYY) I have a sample code: conv <- function(a) { dd <- strsplit(a,"/")[[1]][2] mm <- strsplit(a,"/")[[1]][1] yyyy <- strsplit(a,"/")[[1]][3] com <- paste(dd,mm,yyyy,sep="/") return(com) } a <- as.character(crime.data$Arrest.Date) conv(a) When I do this, I get converted date but only one. That is,

问题 I found that this gives a wrong date. but how i can not solve it. please someone help me. I am new in android Development. Thanks in advance; String timestamp = "1538970640"; SimpleDateFormat formatter = new SimpleDateFormat("dd MMM 'at' hh:mm a z" ); String dateString = formatter.format(new Date(Long.parseLong(timestamp))); This returns: 19 Jan at 01:29 AM GMT+06:oo But it should be: 8 Oct at 9:50 AM GMT+06:00 回答1: The java.util.Date constructor accepts milliseconds since the Epoch, not

问题 I have DF$Date in the as.Date format "yyyy-mm-dd" as shown below. Is there an easy way to get these grouped by month in ggplot? Date 2015-07-30 2015-08-01 2015-08-02 2015-08-06 2015-08-11 2015-08-12 I've added a column DF$Month as "year Monthname" (e.g. April 2015.) I'm doing this by DF$Month<-strftime(DF$Date,format="%B %Y") Is there a quick way to factor the month/years so that they are ordinal? I used a workaround by formatting using: DF$Month<-strftime(DF$Date,format="%Y-%m") so that the
