This looks like an excel datetime format. This is called a serial date. To convert from that serial date you can do this: data[‘Date’].apply(lambda x: datetime.fromtimestamp( (x – 25569) *86400.0)) Which outputs: >>> data[‘Date’].apply(lambda x: datetime.fromtimestamp( (x – 25569) *86400.0)) 0 2013-02-25 10:00:00.288 1 2013-02-26 10:00:00.288 2 2013-02-27 10:00:00.288 3 2013-02-28 10:00:00.288 To assign it … Read more
This is useful—it does the same thing as DateTime.Parse, BUT DOES NOT THROW ANY EXCEPTIONS It returns true if the parse succeeded, and false otherwise. protected void Foo() { // Use DateTime.TryParse when input is valid. string input = “2014-02-02T04:00:00″;//”2014-02-02”; DateTime dateTime; if (DateTime.TryParse(input, out dateTime)) { lblresult.Text = dateTime.ToString(); } else { lblresult.Text = … Read more
store the date time format in YYYY-MM-DD H:I:S, so you can easily SELECT * FROM table_name WHERE start_datetime BETWEEN value1 AND value2 AND end_datetime BETWEEN value1 AND value2; 3 solved Between And Greater Than Date Should Be Implement In Same Query [closed]
there could be a better way to do this.. But this is one way of doing it. import pandas as pd def checkDates(d): if d.time().hour < 6: return d – pd.Timedelta(days=1) else: return d ls = [“12/31/2019 3:45:00 AM”, “6/30/2019 9:45:00 PM”, “6/30/2019 10:45:00 PM”, “1/1/2019 4:45:00 AM”] df = pd.DataFrame(ls, columns=[“dates”]) df[“dates”] = df[“dates”].apply(lambda … Read more
You can use t in format specifier on DateTime‘s format function. date format specifiers format character: t Description: Number of days in the given month Example returned values: 28 through 31 <?php $input=”2017-08-28 10:50:30″; $date_time = DateTime::createFromFormat(‘Y-m-d H:i:s’, $input); $last_day_of_month = $date_time->format(‘Y-m-t H:i:s’); echo $last_day_of_month; This gives: 2017-08-31 10:50:30 Demo: https://eval.in/844314 0 solved Call to … Read more

The seems like the date/time wire format used in WCF. From MSDN it states: DateTime values appear as JSON strings in the form of “/Date(700000+0500)/”, where the first number (700000 in the example provided) is the number of milliseconds in the GMT time zone, regular (non-daylight savings) time since midnight, January 1, 1970. The number … Read more
The pseudo-code would be: if (vacationDayDate.Year == year) { if({isHalfDay}) yearMonths[vacationDayDate.Month] += 0.5; else // is full day yearMonths[vacationDayDate.Month]++; } Or more succinctly: if (vacationDayDate.Year == year) { yearMonths[vacationDayDate.Month] += {isHalfDay} ? 0.5 : 1.0; } 7 solved How to make my calculation more accurate
Your format should be yyyy-MM-dd HH:mm:ss.fff string testDateRaw = @”2014-05-21 10:08:15.965″; string format = “yyyy-MM-dd HH:mm:ss.fff”; DateTime testDate = DateTime.ParseExact(testDateRaw, format, CultureInfo.InvariantCulture); System.Console.WriteLine(testDate); See: Custom Date and Time Format Strings solved DateTime.ParseExact() – DateTime pattern ‘y’ appears more than once with different values
A MySQL query command with this WHERE clause will find the records you want. WHERE lastdatechangeoil <= NOW() – INTERVAL 3 MONTH as long as that information is stored in a DATETIME or TIMESTAMP column. solved Getting all entries in a particular number of months [closed]
DateTime has milliseconds, the MSDN for DateTime Even gives an example: DateTime date1 = DateTime.Now; Console.WriteLine(“Date with milliseconds: {0:MM/dd/yyy hh:mm:ss.fff}”, date1); The fff is milliseconds in the format string. 5 solved I need to know the exact date with millisecond in C# [closed]
It looks like you are trying to get a count of all users who registered on a certain day. If so, I think you are best off using the group keyword to group together all users by registration date. You can then create a new anonymous type to contain by the date, and the count, … Read more
Lets work backwards here – your stored proc will never work, you have not specified a field for the where, and it has 2 missing close parentheses. select * from MyTable where between CAST(@startDate AS VARCHAR(100) and CAST(@EndDateAS VARCHAR(100) should be select * from MyTable where SOMEFIELD between CAST(@startDate AS VARCHAR(100)) and CAST(@EndDateAS VARCHAR(100)) In … Read more
