About the months converter

One month (mo) is approximated here as 30.44 days to keep calculations consistent across conversions and timezones.

Why it matters

Months are a handy unit for planning, billing cycles, and roadmaps. Using an average length avoids large jumps caused by variable month lengths.

Typical conversions

  • mo → Date: turn months into a rough timestamp from the UNIX epoch
  • mo → ms / s / min / h / d / wk: scale to common units
  • mo → years / centuries: approximate longer spans
