Q: The exact origin of the 260-day count is not known, but there are several theories. One theory is that the calendar came from mathematical operations based on the numbers thirteen and twenty, which were important numbers to the Maya. The numbers multiplied together equal 260. Another theory is that the 260-day period came from the length of human pregnancy. This is close to the average number of days between the first missed menstrual period and birth, unlike Naegele's rule which is 40 weeks between the last menstrual period and birth. It is postulated that midwives originally developed the calendar to predict babies' expected birth dates. A third theory comes from understanding of astronomy, geography and paleontology. The mesoamerican calendar probably originated with the Olmecs, and a settlement existed at Izapa, in southeast Chiapas Mexico, before 1200 BCE. There, at a latitude of about 15 N, the Sun passes through zenith twice a year, and there are 260 days between zenithal passages, and gnomons , were found at this and other sites. The sacred almanac may well have been set in motion on August 13, 1359 BCE, in Izapa.
How many days longer is Naegele's pregnancy than 260 days?
A: 20

Q: Hoping to add to a six-game winning streak, the Broncos returned home for an interconference duel with the Tampa Bay Buccaneers. The Broncos grabbed the early lead, when defensive tackle Mitch Unrein, lining up as a fullback, caught a 1-yard touchdown pass from quarterback Peyton Manning. The Buccaneers responded, with a 31-yard field goal by placekicker Connor Barth, then grabbed the lead at the end of the first quarter, with quarterback Josh Freeman connecting on an 11-yard touchdown pass to tight end Dallas Clark. After a scoreless second quarter, the Broncos re-claimed the lead for good with 21 unanswered points, consisting of two Manning touchdown passes to wide receiver Demaryius Thomasfrom 8 and 10 yards, followed by linebacker Von Miller returning an interception off Freeman 26 yards for a touchdown. After a Manning interception late in the third quarter, a 50-yard field goal by Barth to begin the fourth quarter narrowed the gap to 28-13, but the Broncos countered with a 31-yard field goal by placekicker Matt Prater. With 4:37 remaining in the game, the Buccaneers tried to rally, with a 55-yard field goal by Barth, followed by a 5-yard touchdown pass from Freeman to wide receiver Mike Williams with 2:39 remaining. However, the Buccaneers' onside kick attempt was unsuccessful, and the Broncos subsequently ran out the clock. With the win, the Broncos exceeded their win total from 2011, and also clinched their second consecutive AFC West division title. This was the 12th division title in the Broncos' franchise history, tying the Oakland Raiders for the all-time lead in AFC West championships since the 1970 AFL-NFL merger. The Broncos also clinched consecutive division titles for the first time since 1986-87.
