The ddate program now has an upstream source. In October 2012, ddate was completely removed from util-linux. In August 2011 however, one of the maintainers of util-linux made ddate optional, and by default omitted. As such, it had been included at least since 1994 in nearly all Linux distributions. It was a part of the util-linux package containing basic system utilities. Implementations ĭdate is a program that prints the current date in the Discordian calendar. Some of these include Discordians for Jesus/Love Your Neighbor Day ( March 25/Discord 11) Jake Day ( April 6/Discord 23 or occasionally May 23/Discord 70), a day to send tongue-in-cheek letters, emails or faxes to an official or bureaucracy Saint Camping's Day ( May 21/Discord 68), a day to make End of Days predictions and share them in social media Eris Day ( May 23/Discord 70), a day to gather and celebrate Goddess Towel Day ( May 25/Discord 72) Mid Year's Day ( July 2/Confusion 37) X-Day ( July 5/Confusion 40) and Multiversal Underwear Day ( August 10/Bureaucracy 3).

Only these eleven dates are named in the Principia Discordia however, Discordians have felt free to invent other holidays which have become popular to varying degrees. There are also Season Holydays on the 50th of each season: Chaoflux, Discoflux, Confuflux, Bureflux, and Afflux. Van Van Mojo Syaday, for Sri Syadasti Zaraday, for Zarathud and Maladay, for Malaclypse the Elder. There are Apostle Holydays on the 5th day of each season, named after the 5 Discordian apostles: Mungday, for Hung Mung Mojoday, for Dr. Tib's Day is considered outside the Discordian week. The result of this is that any given day of the year in the Discordian calendar may be taken to correspond to the same day of the year in the Gregorian calendar, and vice versa, although some users of the calendar believe that it is tied to the Julian calendar and so will diverge from the Gregorian in 3266 YOLD (AD 2100). This is because 4 years + 1 day = 5, a holy number, but the Discordian leap year also coincides with the Gregorian one. There are 73 of these weeks per year and every year begins with Sweetmorn.Įvery fourth year in the Discordian calendar, starting in 2 YOLD, an extra day is inserted between Chaos 59 and Chaos 60 called St. The days of the week are named after the five basic Discordian elements: Sweet, Boom, Pungent, Prickle, and Orange. The Erisian week consists of five days: Sweetmorn, Boomtime, Pungenday, Prickle-Prickle, and Setting Orange. The Discordian year is aligned with the Gregorian calendar and begins on January 1, thus ChYOLD is JanuGregorian. As described in the Principia Discordia, the Discordian calendar has five 73-day seasons: Chaos, Discord, Confusion, Bureaucracy, and The Aftermath. SELECT DATEADD(day, AS int) – 1, CONVERT(datetime, + ‘0101’, 112))Įasy stuff really, just a matter of thinking about what we mean by a particular format. The second half can be cast to a number, and then added back (subtracting one to get the maths right) using DATEADD. SELECT first bit becomes the year easily enough I’m going to assume we have a char(5) called need to split the string up first. SELECT AS CHAR(4)),2) + RIGHT(‘000’ + CAST(DATEPART(dy, AS varchar(3)),3)Ĭonverting back again isn’t too hard – it’s just a matter of pulling the numbers out of the 5-character string.
SELECT RIGHT(‘000’ + CAST(DATEPART(dy, AS varchar(3)),3)Ĭoncatenating the YY and the DDD, we now have a TO_JULIAN function. We also need to pad the DDD with zeroes – which I’ll do by putting three zeroes in front of the number and getting the three rightmost characters. SELECT RIGHT(CAST(DATEPART(yy, AS char(4)),2) SELECT DATEPART(yy, DATEPART(dy, to make sure that we have the year in two-digits only, we should convert this to a string and get the rightmost two characters. Using the date type in SQL 2008 would work just the same. I’m going to use as a variable here, of type datetime. YY for the year, and DY for the day of the year.
Using the DATEPART function can get each part. So we’re wanting to express a date as YYDDD, where YY is the two-digit form of the year, and DDD is the number of days since Dec 31st of the previous year (ie, the DDDth day of the year). SQL Server doesn’t have a TO_JULIAN function, but we can make one easily enough. People have differing opinions about what Julian means, but the one I got asked about most recently meant YYDDD, as often used by mainframe systems (I think this is Julian Date, as opposed to Julian Day which is the number of days since 4713BC).

I often get asked how to convert a datetime into Julian Date format in T-SQL.
