I found this solution to be good. (This uses the python-dateutil extension) from datetime import date from dateutil.relativedelta import relativedelta six_months = date.today() + relativedelta(months=+6) The advantage of this approach is that it takes care of issues with 28, 30, 31 days etc. This becomes very useful in handling business rules and scenarios (say invoice … Read more
JavaScript itself has terrible Date/Time API’s. Nonetheless, you can do this in pure JavaScript: Date.prototype.addHours = function(h) { this.setTime(this.getTime() + (h*60*60*1000)); return this; }
Congratulations, you’ve hit my favorite pet peeve with JDBC: Date class handling. Basically databases usually support at least three forms of datetime fields which are date, time and timestamp. Each of these have a corresponding class in JDBC and each of them extend java.util.Date. Quick semantics of each of these three are the following: java.sql.Date … Read more
Simple check to see if two time periods overlap: bool overlap = a.start < b.end && b.start < a.end; or in your code: bool overlap = tStartA < tEndB && tStartB < tEndA; (Use <= instead of < if you change your mind about wanting to say that two periods that just touch each other … Read more
I prefer using the dateutil library for timezone handling and generally solid date parsing. If you were to get an ISO 8601 string like: 2010-05-08T23:41:54.000Z you’d have a fun time parsing that with strptime, especially if you didn’t know up front whether or not the timezone was included. pyiso8601 has a couple of issues (check … Read more
You can use the date function: date(“Y-m-d H:i:s”);
Use an extension method. They’re the answer to everything, you know! 😉 public static class DateTimeExtensions { public static DateTime StartOfWeek(this DateTime dt, DayOfWeek startOfWeek) { int diff = (7 + (dt.DayOfWeek – startOfWeek)) % 7; return dt.AddDays(-1 * diff).Date; } } Which can be used as follows: DateTime dt = DateTime.Now.StartOfWeek(DayOfWeek.Monday); DateTime dt = … Read more

The previous answers are correct but it’s generally a better practice to do: import datetime Then you’ll have, using datetime.timedelta: date_1 = datetime.datetime.strptime(start_date, “%m/%d/%y”) end_date = date_1 + datetime.timedelta(days=10)
Short answer Date input = new Date(); LocalDate date = input.toInstant().atZone(ZoneId.systemDefault()).toLocalDate(); Explanation Despite its name, java.util.Date represents an instant on the time-line, not a “date”. The actual data stored within the object is a long count of milliseconds since 1970-01-01T00:00Z (midnight at the start of 1970 GMT/UTC). The equivalent class to java.util.Date in JSR-310 is … Read more
