Grails : Difference b/w two dates with fine-grained details
Hi Friends,
To retrieve difference between two dates with finer details which would display their difference as 2 years 7 weeks 3 days 2 hours 5 mins ago is given below.
/**
* Returns differnce b/w new Date and old date as Map holding difference in years, weeks, days, hrs, mins & secs
*/
public static Map getDiffernceInDates(Date oldDate, Date newDate = new Date()) {
Long difference = newDate.time - oldDate.time
Map diffMap =[:]
difference = difference / 1000
diffMap.seconds = difference % 60
difference = (difference - diffMap.seconds) / 60
diffMap.minutes = difference % 60
difference = (difference - diffMap.minutes) / 60
diffMap.hours = difference % 24
difference = (difference - diffMap.hours) / 24
diffMap.years = (difference / 365).toInteger()
if(diffMap.years)
difference = (difference) % 365
diffMap.days = difference % 7
diffMap.weeks = (difference - diffMap.days) / 7
return diffMap
}
The taglib to display the date difference in detail is given below
def timeDiffInDetail = {attrs ->
Map diff = DateUtil.getDiffernceInDates(attrs.oldDate, attrs.newDate ?: new Date())
String result = diff.years ? diff.years + " years " : ""
result += diff.weeks ? diff.weeks + " weeks " : ""
result += diff.days ? diff.days + " days " : ""
result += diff.hours ? diff.hours + " hours " : ""
result += diff.minutes ? diff.minutes + " minutes ago" : ""
if (result)
out << result
else
out << " 0 minutes ago"
}
Hope this helpled!
Cheers!

you can directly use for calculate days or month or week or year –
static def daysBetweenTwoDate(def startDate, def endDate) {
use(groovy.time.TimeCategory) {
def duration = endDate – startDate
return duration.days
}
}
Cool stuff…..you guys rock!!
Thanks a lot dear. It really helped me….
Iam really appreciate with this blog,and have fulfilled the most of my requirement.But is this possible to find the difference in months from the above code.
I would be thankful to you if you can provide me some guideline over that.
