How to convert baktuns to minutes

To convert baktuns to minutes, multiply the number of baktuns by 207,360,000. This factor is exact. To go the other way, multiply minutes by 4.822530864×10⁻⁹ (rounded).

minutes = baktuns × 207,360,000

Example: 10 baktuns = 2,073,600,000 minutes.

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.

About these units

Baktun (baktun)

MayaHistorical unit (no longer in standard use)

20 katuns or 144,000 days (about 394 years). The Long Count completed 13 baktuns on 21 December 2012, a date misread as a doomsday prediction.

The largest unit in everyday Long Count use, the baktun spans 20 katuns, or 144,000 days, about 394.26 tropical years. Dates are written with the baktun count first, so a monument reading 9.15.10.0.0 sits in the ninth baktun, and the Classic period of Maya civilization fell mainly in the eighth and ninth.

Public attention came when the count reached 13.0.0.0.0 on 21 December 2012, under the widely used GMT correlation. Popular writers called it the end of the world, but scholars note there is no evidence the Maya expected that, and the count simply moved on to 14.0.0.0.0. The next such milestone falls in March 2407.

A naming quirk follows from the numbering. The Long Count starts counting from zero, so the baktun that began in 2012 is strictly the fourteenth, though it is usually called the thirteenth. J. Eric S. Thompson judged that usage inaccurate but too entrenched to change. Larger cycles such as the piktun, at 20 baktuns, are rarely attested, and their names are modern coinages.

1 baktun = 12,441,600,000 seconds (exactly).

Minute (min)

Metric (SI)Current unit

60 seconds. Defined as one sixtieth of an hour.

Minute means small, not short. It comes from the Latin pars minuta prima, the first small part, produced when sixty-based division was applied to the hour. Al-Biruni is credited with dividing the hour into minutes, seconds, thirds and fourths around the year 1000, and Roger Bacon used the same scheme in 1267. For everyday life the minute needed hardware: Jost Bürgi is said to have made the first clock with a minute hand, for Tycho Brahe in 1577, and watches got minute hands only after Thomas Tompion's hairspring of 1675 made them accurate enough.

A minute is 60 seconds, exactly 1/60 of an hour, and the BIPM's SI Brochure is the reference for its symbol, min. Civil timekeeping can bend the rule: because of leap seconds, a UTC minute occasionally holds 61 seconds. A negative leap second would produce a 59-second minute, but that has never happened in more than 40 years. People use the minute for cooking, lectures and phone calls, and the same name serves for the arcminute, which is a sixtieth of a degree.

1 minute = 60 seconds (exactly).
