leap year

it’s a lucky bonus leap year day today. i find the whole thing a little puzzling.
one thing that dissappoints me (other than spelling words correctly) is that they chose February as the month to have the extra day.
why didn’t they put it in june/july/august ? that would make the summer last longer and may even coincide with prebooked holidays thus giving an extra day.
at the very least it should be a public ‘bonus day’ holiday.
all it does stuck on the end of february is postpone the summer for an extra day (and lengthens the winter).
who makes up these rules anyway ?
there’s an excellent page on leap days and wonky calendars here
