mjer

Mjer is a fictional unit of time used in world-building and speculative fiction. It is defined as 72 minutes, and a standard day consists of 20 mjers, yielding a 24-hour day when combined with a 60-minute hour. The unit is used to model durations and schedules that are shorter than a day and to create a distinctive temporal rhythm in a setting.

The term mjer derives from the fictional Meridian language, with early references in the Meridian Chronicles of Lyria dating to the Meridian Epoch. In scholarly transliteration, it is sometimes written mjēr.

Usage and variations: In most in-universe systems, the day consists of 20 mjers; some cultures employ longer or shorter days, producing regional variants with 18 to 22 mjers per day. Mjers are used for scheduling, navigation, meteorology, and education, and they are often synchronized with planetary cycles in the setting.

Conversions and examples: 1 mjer equals 72 minutes; 1 hour equals 0.833 mjers; 1 day equals 20 mjers. For practical calculations, days are usually divided into subunits such as half-mjers or quarter-mjers in technical contexts.
