Increment date to the next day using Groovy - datetime

Trying to add 1 day to the simple date format.
import java.text.SimpleDateFormat
Date date = new Date();
def dateformat = new SimpleDateFormat("YYYY-MM-dd")
def currentDate = dateformat.format(date)
log.info "Current Date : " + currentDate
Date date1 = (Date)dateformat.parse(currentDate);
Calendar c1 = Calendar.getInstance();
c1.setTime(date1);
log info c1.add(Calendar.Date,1);
Error occurred in line :
"log info c1.add(Calendar.Date,1);"
groovy.lang.MissingPropertyException:No such property: info for class: Script16 error at line: 10
Note : The current date should be any date in future and i want to increment by 1 day.

You can use TimeCategory to add the day as shown below:
use(groovy.time.TimeCategory) {
def tomorrow = new Date() + 1.day
log.info tomorrow.format('yyyy-MM-dd')
}
EDIT: based on OP comments
Here is another away which is to add method dynamically, say nextDay() to Date class.
//Define the date format expected
def dateFormat = 'yyyy-MM-dd'
Date.metaClass.nextDay = {
use(groovy.time.TimeCategory) {
def nDay = delegate + 1.day
nDay.format(dateFormat)
}
}
//For any date
def dateString = '2017-12-14'
def date = Date.parse(dateFormat, dateString)
log.info date.nextDay()
//For current date
def date2 = new Date()
log.info date2.nextDay()

Well, the error you provide clearly tells you, that you have a syntax error. It says that there is no property info.
This is because you write
log info c1.add(Calendar.Date,1);
instead of
log.info c1.add(Calendar.Date,1);
If you would have used the correct syntax, it would complain that Calendar has no property Date.
So instead of
c1.add(Calendar.Date, 1)
you meant
c1.add(Calendar.DAY_OF_MONTH, 1)
But in Groovy you can even make it easier, using
c1 = c1.next()

How to use for loop to create multiple dates?

I have a function here that gets the date, and adds one week to it:
func thingy() {
let currentDate = Date()
var dateComponent = DateComponents()
dateComponent.day = 7
let futureDate = Calendar.current.date(byAdding: (dateComponent*i), to: currentDate)
print(futureDate!.formatted())
}
This gets the current date, adds one week to it, and prints out that date.
I want to get a for loop that will give the date, for example maybe 10 weeks in the future, maybe looking something like this:
for i in 1...num[ex: 11] {
let currentDate = Date()
var dateComponent = DateComponents()
dateComponent.day = 7
let futureDate = Calendar.current.date(byAdding: (dateComponent*i), to: currentDate)
let match = (title: "Test", date: futureDate)
}
I get this error:
Referencing operator function '*' on 'DurationProtocol' requires that 'DateComponents' conform to 'DurationProtocol'
How do I fix this?
I would advise adding .weekOfYear to the date. E.g., to get an array of Date representing the next ten weeks:
let calendar = Calendar.current
let today = calendar.startOfDay(for: Date())
let dates = (1 ... 10)
.compactMap { calendar.date(byAdding: .weekOfYear, value: $0, to: today) }

Parse date to "yyyy-MM-dd'T'00:00:00" using Groovy

I am trying to parse date format '2017-12-18T20:41:06.136Z' into "2017-12-18'T'00:00:00"
Date date = new Date();
def dateformat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
dateformat.setTimeZone(TimeZone.getTimeZone(TimeZoneCode));
def currentDate = dateformat.format(date)
log.info "Current Date : " + currentDate
date1 = new SimpleDateFormat("yyyy-MM-dd'T'00:00:00").parse(currentDate)
log.info "Current Date : " + date1
Error displayed :
java.text.ParseException: Unparseable date: "2017-12-18T20:46:06:234Z" error at line: 16
This line gives error :
date1 = new SimpleDateFormat("yyyy-MM-dd'T'00:00:00").parse(currentDate)
Running Groovy on Java 8 gives you access to the much better Date/Time classes... You can just do:
import java.time.ZonedDateTime
import java.time.format.DateTimeFormatter
import java.time.temporal.ChronoUnit
String result = ZonedDateTime.parse("2017-12-18T20:41:06.136Z")
.truncatedTo(ChronoUnit.DAYS)
.format(DateTimeFormatter.ISO_LOCAL_DATE_TIME)
In order to avoid the mentioned error, use below statement Date.parse(..):
def dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
def dateString = "2017-12-18T20:41:06.136Z"
def date = Date.parse(dateFormat, dateString)
You should be able to achieve what you are trying to using below script.
//Change timezone if needed
def tz = 'IST'
TimeZone.setDefault(TimeZone.getTimeZone(tz))
def dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
def dateString = "2017-12-18T20:41:06.136Z"
Calendar calendar = Calendar.getInstance()
calendar.with {
time = Date.parse(dateFormat,dateString)
set(Calendar.HOUR_OF_DAY, 0)
set(Calendar.MINUTE, 0)
set(Calendar.SECOND, 0)
set(Calendar.MILLISECOND, 0)
}
log.info calendar.time.format(dateFormat)

if you need to parse only part of date, use the following syntax:
Date.parse("yyyy-MM-dd'T'HH:mm:ss",'2017-12-18T16:05:58bla-bla')

Javascript Moment.js add a day to a date in milliseconds

I am trying to add a day to a date in milliseconds.
The code I am using is bellow.
var x = 1450612800000;
var timeFrame = 'days'
x = moment(x).add(timeFrame, 1);
console.log(x['_i']) //returns 1450612800000
Here is the fix:
var x = 1450612800000;
var timeFrame = 'd'
var newDay = moment(x).add(tf, 1);
console.log('newDay');
//Get New Date in Milliseconds format
console.log(newDay.valueOf());
//Get New Date in Date Format
console.log(newDay.toDate());
Take a look at this StackOverflow answer: https://stackoverflow.com/a/28132227/3692354
_i isn't what you want to use here - that's the input that was used to create the moment object. I think what you want to use instead is moment's valueOf function: http://momentjs.com/docs/#/displaying/unix-offset/

datetime parsing from excel sheet in asp.net

i want to get a datetime value from excel sheet and take the highest and the lowest date
i read the excel sheet and put it in datatable :
i tried this code :
protected void CheckTheFP(DataTable data)
{
if (data.Rows.Count != 0)
{
DateTime ds = new DateTime();
err.Text = DateTime.TryParseExact(data.Rows[0][2].ToString(), "MM/dd/yy hh:mm tt",
CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out ds) + "" ;
}
}
but i always get false ... don't know why ?
and is there a way to sort this datatable or take the highest and lowest date
this the excel sheet i read from
This format string should work: "M/dd/yy h:mm tt". I've used single M because the month has one digit, the same applies to the hours. I've used CultureInfo.InvariantCulture to prevent that all / will be replaced with your actual date-separator (in case that it's different).
You can use LINQ:
var allDateTimes = data.AsEnumerable()
.Select(row => DateTime.ParseExact(row.Field<string>("Time"), "M/dd/yy h:mm tt", CultureInfo.InvariantCulture));
DateTime min = allDateTimes.Min();
DateTime max = allDateTimes.Max();
If you want to be on the safe side you should use TryParseExact, for example with this code:
IEnumerable<DateTime> allDateTimes = data.AsEnumerable()
.Select(row => {
string time = row.Field<string>("Time").Trim();
DateTime dt;
if (DateTime.TryParseExact(time, "M/dd/yy h:mm tt", CultureInfo.InvariantCulture, DateTimeStyles.None, out dt))
return (DateTime?) dt;
return null; // set a breakpoint here to see which value could not be parsed
})
.Where(dt => dt.HasValue)
.Select(dt => dt.Value);
DateTime min = allDateTimes.Min();
DateTime max = allDateTimes.Max();
Edit: you: "when i try to use it on the date 11/2/14 4:42 PM you see the 11 is not in M datetime format
The month is not the problem. Use single d instead because the days can have a single digit also.
So: "M/d/yy h:mm tt"

How to get end date

How to get End Date after selection of Start date from drop down list.
I am selecting startdate from dropdowns and I am showing last date in label.
For example- If I am selecting "January" from first dropdown. Date "1" from second dropdown.
Then Label1.text become last date i.e. 31 december.
How can I do this ?
Please try below code
int month = DateTime.ParseExact(Convert.ToString(ddlMonth.SelectedValue), "MMMM", CultureInfo.CurrentCulture).Month;
int day = Convert.ToInt32(ddlDay.SelectedValue);
int year=DateTime.Now.Year;
DateTime date = new DateTime(year,month, day);
//Use AddDays for add and substract days
date.AddDays(-1);
string str=String.Format("{0:m}", date);
There are many ways of doing it . You can do it in javascript as well as in asp.net. have a page method of make a $.ajax call with the data selected
$.ajax({
url : '',
data : 'month=MONTH&day=DAY',
success : function(result){
$("#labelid").text(result);
}
})
C# part
int maxDay = DateTime.DaysInMonth(DateTime.Now.year,month);
//validate the selected day is equal or less than the maxDay
DateTime StartDate = new DateTime(DateTime.Now.Year, Convert.ToInt16(dropdownMonth.SelectedIndex) + 1, Convert.ToInt16(dropdownDays.SelectedIndex) + 1);
DateTime PreDayDate = StartDate.AddDays(-1); lblEndDateValue.Text = PreDayDate.ToString();
In case you do not want to do AJAX you have to do the postback and handle it then onward.
using
DateTime.AddDays Method
you can do this
DateTime StartDate = new DateTime(DateTime.Now.Year, Convert.ToInt16(UrMonthNameDropDown.SelectedIndex+1), Convert.ToInt16(UrDateDropdown.SelectedIndex));
DateTime PreDayDate = StartDate.AddDays(-1);
substract 1 day from your start date.
