There are no known primes with period 365, while at least one prime with each of the periods 1 to 364 is known.

## Timekeeping

There are 365.2422 solar days in the mean tropical year. Several solar calendars have a year containing 365 days.[1] Related to this, in Ontario, the driver's license learner's permit used to be called "365"[2][3] because it was valid for only 366 days. Financial and scientific calculations often use a 365-day calendar to simplify daily rates.

## Religious meanings

### Judeo-Christian

In the Jewish faith there are 365 "negative commandments".[4] Also, the Bible states that Enoch lived for 365 years before entering heaven alive (see Genesis 5:23-24).

### Gnosticism

The letters of the deity Abraxas, in the Greek notation, make up the number 365. This number was subsequently viewed as signifying the levels of heaven.[5]
