Summing temperature durations

Highs and lows on weather forecasts only gives a vague sense of the weather. For example, deserts might reach over 100 degrees Fahrenheit, however that's often times counter balanced with very cold nights.

A better sense would be in the form temperature duration.

For example this forecast:
City A high 88, low 70
City B high 100, low 50

One might think city B has hotter weather, but say these are the durations
City A day: 10 hours in the 80s and 14 hours in the 70s
City B day: 1 hour in the 100s, 3 hours in the 90s, 4 hours in the 80s, 4 hours in the 70s, 8 hours in the 60s, 4 hours in the 50s.

Perhaps the integral under a curve could be stated for forecasts, sort of like how much area under a temperature/time curve.

Also for temps over 80degF or so humidity becomes an important factor. 100degF @ 15 humidity is more tolerable than is 80degF @ 85% humidity due to the amount of evaporation of liquid on the skin which has a strong cooling effect.

Proposed Metric Calendar

(link to part 2 http://www.polarjetstream.com/2019/08/proposed-metric-calendar-part-2.html )

See a metric calendar for any month/year using this new JavaScript program (made in 2019 Aug)
https://warpdrive.github.io/JavaScript-Metric-Calendar-2019/metric%20calendar.htm
This calendar is zero based, meaning day of year and day of month both start at zero instead of at 1. You can multiply week by 10 to get the day of year. In fact you can simply forgo months and simply identify days using weeks to the 0.1 precision.

-Always: First day of the month is the first day of the week
-Always: Last day of the month is the last day of the week
-Always: Exactly 3 weeks per month
-Always: Exactly 9 weeks per season
-Always: Day of Month always falls on the same day of week.
-Always: Day of Year simply equals week of year * 10
-Leapday at end of the year as to not disturb the consistent order of a year
-Take 3 days off from work a metric week (off 30% of the days, about the same % as now)
-Matching January 1st of the current calendar to this proposed metric calendar seems best.
-Calendar seasons begin roughly 10 days after the corresponding solstice/equinox (align with months)
