Seconds to Months
Approximate "months"
This calculator treats one month as exactly 30 days (60×60×24×30 seconds)—a blunt instrument shared by many billing scripts. Real calendar months vary (28–31); finance leases use day-count conventions instead.
When to use it
Rough SaaS tenure math or comparing vendor quotes that price "per 30-day month." For week-accurate spans prefer Seconds to Weeks; invert via Months to Seconds.
