概要

Go言語の json packageには不思議な値がある。これはなにか。 

https://github.com/golang/go/blob/11f11f2a00aa3149a6ea69a50e7b7b429cf368b7/src/encoding/json/v2/arshal_time.go#L469-L473

// daysPerYear is the exact average number of days in a year according to
// the Gregorian calender, which has an extra day each year that is
// a multiple of 4, unless it is evenly divisible by 100 but not by 400.
// This does not take into account leap seconds, which are not deterministic.
const daysPerYear = 365.2425
