Weeks to months converter
Weeks and calendar months do not line up in a fixed whole-number ratio, so converting between them requires a stated approximation.
Run — free
This weeks-to-months calculator treats a year as the Gregorian average of 365.2425 days, divides that year into twelve equal average months, and converts the supplied number of seven-day weeks on that basis. The result is useful for planning, reporting, study schedules, project timelines, and other situations where an approximate month value is more readable than a week count. Enter any finite, non-negative number of weeks, including a decimal, and the capability returns the equivalent number of average months. It does not inspect dates or guess calendar boundaries.

For developers — API access
Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.
API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.
