Some material is very old and may be incorrect today © April 2011 Tony Lawrence (This post is an update and rewrite of something written several years back) Scripts sometimes have to deal with relative dates - yesterday and tomorrow are the most troublesome because of variations in the number of days in the month, oddities like leap year and so on.
You can write all that out in code ("If it's now the first, decrement the month.
(One final note - the example code above shows output in my locale.
In your locale it may differ - this is on purpose, of course!
Your international users won't be using the same date/time format you're using and it won't pick up user preferences (e.g., date order or 12-hour vs 24-hour). Date Format (not to be confused with the previous Date Format).
There are some methods here that return formatters defined by the system's locale, like get Date Format() and get Time Format()(among others): The problem with these formatters is that they are inflexible; what if you don't want to show a year on a date? There are only limited circumstances where these formatters are good enough. It has two powerful methods - [format Date Time()]( Utils.html#format Date Time(android.content.
If the month is now 0, make it 12..") but that's cumbersome and seldom needed. BSD systems like Mac OS X don't have that, but they do have "-v" modifiers, and although I may be a bit prejudiced, I like them better. For yesterday: # I did this on April 19th, 2011 $ date -v2010y # move to 2010 Mon Apr 19 EDT 2010 $ date -v2010y -v3m # and then to March Fri Mar 19 EDT 2010 $ date -v2010y -v3m -v1d # and then to March 1st Mon Mar 1 EST 2010 $ date -v2010y -v3m -v1d -v-1d # now go back one day Sun Feb 28 EST 2010 $ date -v2008y -v3m -v1d -v-1d # same thing for 2008 (a leap year) Fri Feb 29 EST 2008 Before we look at some of the more difficult ways to manipulate dates, a word of caution is in order: when people ask for something from "yesterday" or "last week", the answer isn't always to subtract one day or seven for a week.
FORMAT_SHOW_DATE); // date == "December 20" date = Date Utils.format Date Time(this, Time In Millis(), Date Utils. Besides being easier, it can optimize output in certain circumstances by reducing redundant field usage, like months/years when they don't change throughout the range: Calendar cal1 = new Gregorian Calendar(2013, 11, 20); Calendar cal2 = new Gregorian Calendar(2013, 11, 25); Calendar cal3 = new Gregorian Calendar(2014, 0, 5); String date = Date Utils.format Date Range(this, cal1Time In Millis(), cal2Time In Millis(), Date Utils.Context, long, int)) and [format Date Range()]( Utils.html#format Date Range(android.content.Context, long, long, int)) - which take in flags to determine which fields to include.It automatically formats to the user's locale and preferences without you having to worry about it.Date Utils.format Date Time() formats a single point in time. FORMAT_SHOW_TIME); // date == ", 12/20/2013" Date Utils.format Date Range() formats a range, like "Jan 5 - Feb 12".
