I wrote Caldroid library (https://github.com/roomorama/Caldroid) that is simple to setup and have many features such as setup min/max date, disabled dates, select date range etc. It’s quite easy to customize the look and feel. Just to share if someone might find it useful 🙂
The basic algorithm is the following: Get the current date Get its day of week Find its difference with Wednesday If the difference is not positive, add 7 (i.e. insist on next coming/future date) Add the difference Here’s a snippet to show how to do this with java.util.Calendar: import java.util.Calendar; public class NextWednesday { public … Read more
tl;dr For a year-week defined by the ISO 8601 standard as starting on a Monday and first week contains the first Thursday of the calendar year, use the YearWeek class from the ThreeTen-Extra library that adds functionality to the java.time classes built into Java. org.threeten.extra.YearWeek .from( LocalDate.of( 2012 , Month.APRIL , 23 ) ) .toString() … Read more
Intent intent = new Intent(Intent.ACTION_EDIT); intent.setType(“vnd.android.cursor.item/event”); intent.putExtra(“title”, “Some title”); intent.putExtra(“description”, “Some description”); intent.putExtra(“beginTime”, eventStartInMillis); intent.putExtra(“endTime”, eventEndInMillis); startActivity(intent);
Your concrete problem is that you migrated from Joda’s zoneless date time instance DateTime to Java8’s zoned date time instance ZonedDateTime instead of Java8’s zoneless date time instance LocalDateTime. Using ZonedDateTime (or OffsetDateTime) instead of LocalDateTime requires at least 2 additional changes: Do not force a time zone (offset) during date time conversion. Instead, the … Read more
I would strongly recommend using Joda Time instead (for all your date/time work, not just this): // TODO: Consider time zones, calendars etc LocalDate now = new LocalDate(); LocalDate monday = now.withDayOfWeek(DateTimeConstants.MONDAY); System.out.println(monday); Note that as you’ve used Monday here, which is the first day of the week in Joda Time, this will always return … Read more
I’ve studied the docs and this is my result: I’ve put a time limit of one month hard-coded, but this is just an example. public void GetAllCalendarItems() { Microsoft.Office.Interop.Outlook.Application oApp = null; Microsoft.Office.Interop.Outlook.NameSpace mapiNamespace = null; Microsoft.Office.Interop.Outlook.MAPIFolder CalendarFolder = null; Microsoft.Office.Interop.Outlook.Items outlookCalendarItems = null; oApp = new Microsoft.Office.Interop.Outlook.Application(); mapiNamespace = oApp.GetNamespace(“MAPI”); ; CalendarFolder = mapiNamespace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderCalendar); … Read more
You can use the Joda Time library to do this pretty easily – I use it for anything time related other than using the standard Java Date and Calendar classes. Take a look at the example below using the library: MutableDateTime epoch = new MutableDateTime(); epoch.setDate(0); //Set to Epoch time DateTime now = new DateTime(); … Read more
Perhaps it is more straightforward to create the trade calendar from scratch, like so: import datetime as dt from pandas.tseries.holiday import AbstractHolidayCalendar, Holiday, nearest_workday, \ USMartinLutherKingJr, USPresidentsDay, GoodFriday, USMemorialDay, \ USLaborDay, USThanksgivingDay class USTradingCalendar(AbstractHolidayCalendar): rules = [ Holiday(‘NewYearsDay’, month=1, day=1, observance=nearest_workday), USMartinLutherKingJr, USPresidentsDay, GoodFriday, USMemorialDay, Holiday(‘USIndependenceDay’, month=7, day=4, observance=nearest_workday), USLaborDay, USThanksgivingDay, Holiday(‘Christmas’, month=12, day=25, observance=nearest_workday) … Read more
You can use date from the datetime module to find the first Sunday in a year and then keep adding seven days, generating new Sundays: from datetime import date, timedelta def allsundays(year): d = date(year, 1, 1) # January 1st d += timedelta(days = 6 – d.weekday()) # First Sunday while d.year == year: yield … Read more
