We want to shift these numbers so we can add them to get our final form > Compiles to: date "Wednesday, Ap00:00:00" AppleScript's Gregorian date range is from midnight of Januto the second before midnight (23:59:59) on December 31, 9999.ĭate_format("12 April 2006") - for example
When the name of the month is given, the day-month order is arbitrary but the year must be last and a period is not required but may be used if the month is abbreviated. In the United Kingdom and much of Europe, the day of the month should precede the month if the month is given numerically, again presuming that the reader has not customized the order, and of course, the name of the month must be in the appropriate language. The numerical examples below work if you have selected "United States" in the System Preferences/International/Formats pane and have not customized them or chosen a calendar other than "Gregorian". All of the numerical forms must follow the International preferences set for the user. but note that in both cases, the result is text, not a dateĪppleScript is rather flexible about what it will coerce to a date as well, but the results depend on your settings in International System Preferences.
Similarly, we can get the "date string", without the time appended to it.ĭate string of (current date) -> "Saturday, April 15, 2006" Time string of (current date) -> "4:29:04 PM" - the time without the date
This is the number of seconds since midnight rather than 4:29:04 PM. In addition, AppleScript will return the current date and time with a simple instruction: "current date" that often needs parentheses around it. The AppleScript's Standard Additions Scripting Addition adds support for a "date" class to AppleScript and date-like strings of text can be coerced to dates by preceding them with the word "date" or following them with "as date". The Fundamentals of AppleScript's Dates & Time Where possible, I have credited the authors of these ideas although they may appear here in slightly modified form. Most of the scripts here are "plain vanilla" AppleScript and do not rely on Scripting Additions or other tools. Possibly no one else in the world will have exactly the same requirements, but hopefully the examples explained in this article will give some idea of the sort of thing that can be done and with minor modifications can be adapted to the reader's task. These are solutions to a few problems that have cropped up in various AppleScript fora over the past few years. However, it's usually possible - with a little mathematical forethought and the exploitation of some of the peculiarities of date variables and AppleScript coercion - to get the required results by much shorter means. For instance, AppleScript doesn't (at the time of writing) provide numerical equivalents for months, so it seems at first that the only way to handle them is to use a look-up list, a repeat loop, and lots of 'if-thens'. This is often just a minor part of what the script actually does, but achieving the result can become a production number in its own right. Scripters often need to identify, predict, or calculate dates in their scripts - for publishing, accounting, labeling files and archives, or finding special dates.
