What is another word for lunar time period?
Pronunciation: [lˈuːnə tˈa͡ɪm pˈi͡əɹɪəd] (IPA) 
The lunar time period, commonly known as a 'month', has many synonyms in the English language. 'Lunar cycle' or 'lunar phase' can be used to describe the continuous change in the Moon's appearance from Earth. 'Synodic month' specifically refers to the 29.5-day cycle of the Moon's phases. 'Sidereal month' is the time it takes for the Moon to return to the same position in relation to the stars, which is slightly longer than a synodic month at 27.3 days. Another synonym is 'lunation', which is a count of the number of times the Moon goes through its full cycle of phases. These terms can be used interchangeably or specifically depending on the context.
