Hello,

I wish all the best for 2006 to all of you. I hope that many of us will
meet at the Mental Calculation World Cup in November in Giessen (see
http://www.recordholders.org/en/events/worldcup/2006/index.html). It
would be nice to send back the entry form if you have the intention to
take part.

It is a pleasure for me to announce that new world records have been
verified for all three calendar computing categories. (see
http://www.recordholders.org/en/records/dates.html) These records will
be published in the "Book of Alternative Records"
(http://www.alternativerecords.co.uk) as well.
Yusnier Viera Romero (Cuba) bettered the record for calculating the day
of the week for dates of one century twice on 31 October 2005 at the
University of Havana. He first achieved 23.2 sec and 19.8 sec in another
attempt. On the same occasion, he calculated 42 days of the week in one
minute for days chosen from the years 1600-2100.
Only a few days later, on 6 November, Matthias Kesselschläger got back
his world records with a time of 17.9 seconds (20 days from one century)
and 45 dates from 1600-2100. Also, he set a record for the 365 days of
2005 in 214 seconds only.

I am looking forward to see the contest between Yusnier and Matthias at
the World Cup, both told me that they want to take part.

Best Wishes,
Ralf
