## Time Interval Conversion
|
|
|
|
In [[2026-01-09_12-00-00]]
|
|
I defined time intervals according to averages
|
|
which are true of the Gregorian calendar for $\lim\limits_{t\to\infty}$,
|
|
but which are not so appropriate for a human lifetime scale.
|
|
|
|
True of the Gregorian calendar (and its predecessors)
|
|
for all time scales:
|
|
|
|
$$
|
|
\begin{align*}
|
|
1~\text{Year} &\equiv 12~\text{Months} \\
|
|
1~\text{Week} &\equiv 7~\text{Days}
|
|
\end{align*}
|
|
$$
|
|
|
|
In 2001--2099 leap years occur exactly once in four years.
|
|
|
|
$$
|
|
\begin{align*}
|
|
1~\text{Year} &= 365.25~\text{Days} \\
|
|
\end{align*}
|
|
$$
