About converting Days to Months
Days (d) and Months (mo) are both units of time, so converting between them is a single multiplication: multiply your Days figure by 0.03285. Ten Days comes to 0.3285 Months, and a hundred works out at 3.2854 Months.
Rule of thumb: going from Days to Months divides, so the figure always shrinks — it takes about 30.4375 Days to make a single Month. If your answer came out bigger, you have the conversion the wrong way round.
What is a Day?
A day is exactly 86,400 seconds — and that is a statement about the unit, not about the Earth. A real solar day varies slightly depending on winds, tides and what the planet’s core is doing, and tidal friction is gradually lengthening it. The gap between the tidy unit and the untidy planet is what leap seconds patch over. Astronomers also distinguish the solar day from the sidereal day, one full rotation relative to the stars, which is about four minutes shorter because the Earth has meanwhile moved along its orbit.
What is a Month?
The month is the messiest unit in everyday use. Gregorian months run from 28 to 31 days for reasons that are pure historical accretion rather than design, so there is no true number of seconds in a month at all. This converter uses an averaged month of 2,629,800 seconds — one twelfth of a Julian year, about 30.44 days — and that is a convention, not a definition: the answer here is an average, not a fact. It is worth remembering that a month in a contract or a subscription almost always means a calendar month rather than thirty days, and the difference decides real billing dates.
To put both in perspective: a day is one turn of the Earth on its axis, while a month is one page of a wall calendar.
