The 22 pages that link to Metonic cycle, each with the reason it gives.

• Babylonian astronomyRelated: Babylonian knowledge of this cycle informed Greek calendrical astronomy.

• Lunar calendarRelated: This relationship offered a practical cycle for coordinating lunar months with seasons.

• Hebrew calendarRelated: The calendar's seven leap years in each 19-year cycle use this close approximation.

• EquinoxRelated: Ancient calendar makers combined lunar cycles with seasonal markers such as the equinox.

• IntercalationRelated: Its near-equality lets lunisolar calendars schedule seven intercalary months in 19 years.

• Leap yearRelated: Lunisolar calendars use this cycle to schedule inserted months.

• CalendarBroader topic: This cycle offers a recurring rule for aligning lunar months with solar years.

• Lunisolar calendarBroader topic: Its pattern of seven added months offers a practical lunisolar correction.

• Antikythera mechanismRelated: The input gears encode this cycle; it synchronizes lunar months with the solar calendar on the dials.

• Synodic monthRelated: 235 synodic months fall just two hours short of nineteen solar years, the arithmetic the cycle exploits.

• Lunar monthRelated: It provided a way to reconcile lunar months with the solar year.

• Calendar reformRelated: Its near-match explains how lunisolar calendars can reconcile lunar months with solar seasons.

• Babylonian calendarNarrower topic: This later cycle formalized the lunar-solar relationship Babylonian astronomers had long managed.

• Full moonRelated: It helps reconcile full-moon dates with recurring seasons in lunisolar calendars.

• Japanese lunisolar calendarRelated: This cycle offers a mathematical model for reconciling lunar months and solar seasons.

• Solar yearRelated: It helped ancient calendars reconcile lunar months with the seasonal year.

• Seven-day weekRelated: It reconciles lunar months and solar years, which the seven-day week does not attempt.

• Saros cycleCompared with: It aligns lunar phases with the solar year but does not reproduce eclipse geometry as the Saros does.

• Christopher ClaviusRelated: Lunar-cycle arithmetic underlies the traditional ecclesiastical calculation of Easter.

• Eclipse cycleCompared with: It aligns lunar phases with calendar dates but does not by itself guarantee repeating eclipses.

• History of calendarsRelated: This cycle offered a regular rule for inserting months into lunisolar calendars.

• NabonassarCompared with: It is a Greek calendrical cycle, distinct from the royal epoch used to date observations.
