Britain did not convert to the Gregorian calendar until 1751, when 11 days had to be added to their dates to get the Gregorian dates. In 1639 they were 10 days behind the Gregorian calendar.
Re: Klein Tools Or Greenlee. Both Klein and Greenlee are TOP quality tools with a niche market. They have a few common tools (such as rabis and ratchet cutters) and either is worth buying over pretty much anything else. They are not really direct competitors. I prefer Knipex for most hand tools except linemans.
Available at specialty dealers, the bikes range in price from $250 to $375 for comfort bikes to $550 to $6,500 for road bikes. Klein Klein is based in Waterloo, Wis., and makes mountain and road bikes mostly for the export market.
