1 tun (Maya) = 518,400 minutes

How to convert tun (Maya) to minutes

To convert tun (Maya) to minutes, multiply the number of tun (Maya) by 518,400. This factor is exact. To go the other way, multiply minutes by 0.000001929012346 (rounded).

minutes = tun (Maya) × 518,400

Example: 10 tun (Maya) = 5,184,000 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

Tun (Maya) (tun)

MayaHistorical unit (no longer in standard use)

18 winals or 360 days, the Maya 'year' of the Long Count.

Eighteen winals, or 360 days, make a tun. Scholars often call it the Long Count year, but it is five days shorter than the 365-day civil year, the haabʼ, and about five and a quarter days shorter than the tropical year of roughly 365.24 days. The tun therefore drifts away from the seasons, and the Maya tracked the solar year separately with the haabʼ.

The tun is the third position from the right in a written Long Count date. Its choice of 18 winals is the reason the system is not purely base-20: a strict base-20 count would have given 400 days at this step. The rounded 360-day figure is close to a year while staying a multiple of 20, which suited arithmetic on 20-day units.

The tun is the building block of the longer cycles. Twenty tuns form a katun, and rulers and events were frequently dated by how many tuns had passed. In seconds it equals 31,104,000, about 0.99 of a modern calendar year.

1 tun (Maya) = 31,104,000 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).
