Assuming you can calculate the date/time range for "today" by following Jon Skeet's advice:
LocalDate today = now.toLocalDate();
LocalDate tomorrow = today.plusDays(1);
DateTime startOfToday = today.toDateTimeAtStartOfDay(now.getZone());
DateTime startOfTomorrow = tomorrow.toDateTimeAtStartOfDay(now.getZone());
Then check if startOfToday <= ...

Rinku, I don't really think you'd want to attempt to rewrite the whole java date/calendar libraries! The easiest thing for you to do would be to use the java.util.Calendar (get an instance by calling the static Calendar.getInstance() method). Calendar has a function Calendar.get(int) which can be used to get the day of week ( mon,tues,...) by using as getInstance(DAY_OF_WEEK). This factors ... |
Simple. Use a Calendar. Set the YEAR to 2004, MONTH to AUGUST, the DAY_OF_WEEK_IN_MONTH to 2, and the DAY_OF_WEEK to WEDNESDAY. Get the time, done. If this confuses you, you might want to study the differences between WEEK_OF_MONTH and DAY_OF_WEEK_IN_MONTH. - Peter [ August 23, 2004: Message edited by: Peter den Haan ] |

You can use Calendar API to get the day of the week.Let's say the date is 6th Aug 2002.Set the calendar object as following: cal.set(2002,7,6); where - 2002 is the year 7 - month (Jan is 0 so Aug is 7) 6 - date import java.util.*; class Test{ public static void main(String args[]){ Calendar cal = Calendar.getInstance(); cal.set(2002,7,6); System.out.println("Day is "+cal.get(cal.DAY_OF_WEEK)); ... |

Look at the Calendar class, it will have all you need. Hint: get the day of the week and the last day of the month--ie Monday and 30, and then you'll know how many slots are left in the week or until the end of the month--which ever comes first. But isn't it true all weeks have 7 days? |

You create a Calendar instance. You then use add, set, and roll methods to change values. Then you get a Date object representing the date you set the calendar to. Then you can use a java.text.SimpleDateFormat to print the date as you like. Read the docs. I think you'll find it's pretty straightforward. |
