Convert month (synodic) to seconds
Month (Synodic)
The synodic month is the average period of the Moon's orbit as measured from one new moon to the next, representing the complete cycle of lunar phases. It is the basis for most historical lunar calendars and is used in astronomical calculations of eclipse cycles. One synodic month equals approximately 29.53059 days.
Second
The second (symbol: s , abbreviation: sec ) is the base unit of time in the International System of Units (SI) (French: Système International d’unités), commonly understood and historically defined as 1/86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analog clocks and watches often have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage of time in seconds. Digital clocks and watches often have a two-digit seconds counter. The second is also part of several other units of measurement like meters per second for velocity, meters per second per second for acceleration, and cycles per second for frequency.
