Artifacts from the Paleolithic suggest that the moon was used to reckon time as early as 6,000 years ago. Lunar calendars were among the first to appear, either 12 or 13 lunar months (either 354 or 384 days). Without intercalation to add days or months to some years, seasons quickly drift in a calendar based solely on twelve lunar months. Lunisolar calendars have a thirteenth month added to some years to make up for the difference between a full year (now known to be about 365.24 days) and a year of just twelve lunar months. The numbers twelve and thirteen came to feature prominently in many cultures, at least partly due to this relationship of months to years. Other early forms of calendars originated in Mesoamerica, particularly in ancient Mayan civilization. These calendars were religiously and astronomically based, with 18 months in a year and 20 days in a month.
Which calendars were among the last to appear?
A: unanswerable

Confer With the White House. If his or her party controls the White House, the minority leader confers regularly with the President and his aides about issues before Congress, the Administration's agenda, and political events generally. Strategically, the role of the minority leader will vary depending on whether the President is of the same party or the other party. In general, minority leaders will often work to advance the goals and aspirations of their party's President in Congress. When Robert Michel, R-IL, was minority leader (1981–1995), he typically functioned as the "point man" for Republican presidents. President Ronald Reagan's 1981 policy successes in the Democratic controlled House was due in no small measure to Minority Leader Michel's effectiveness in wooing so-called "Reagan Democrats" to support, for instance, the Administration's landmark budget reconciliation bill. There are occasions, of course, when minority leaders will fault the legislative initiatives of their President. On an administration proposal that could adversely affect his district, Michel stated that he might "abdicate my leadership role [on this issue] since I can't harmonize my own views with the administration's." Minority Leader Gephardt, as another example, has publicly opposed a number of President Clinton's legislative initiatives from "fast track" trade authority to various budget issues.
Is the minority leader's strategic role always consitent?
A: will vary depending on whether the President is of the same party or the other party
