## How many days are there in May?

The month of May has 31 Days. Here you can find out the length of all months in days and memory aids.

### Generally

The term month comes from the word "Moon" since one month roughly corresponds to one moon phase (29.5 days). The twelve Months result in one year - the time it takes the earth to orbit the sun once. A year has 365 or 366 days.

Most months have 31 days, followed by 30 days - February has 28 or 29 days (leap year) to correct the earth's mean period (365.2425 days) around the sun.

### Reminder: How many days are there in a month?

We found the following little donkey bridge on the Internet:

November has 30 days,
with April, June and September.
At 28 only one follows
and the others have 31.

... in English it rhymes a little better:

Thirty days have September,
April, June and November.
All the rest have 31,
except February which has 28.

### Hand knuckles donkey bridge

With the knuckle donkey bridge, it works like this:

You just start with the first ankle, then the deepening follows, then the ankle again, etc. The first knuckle is January, the deepening February (28 or 29 days) etc. - except for February, all deepening means 30 days.
