If they are truly independent of each other some of the uncertainty cancels out. 10 people and a budget of $1/person are both unlikely events, and two unlikely events occurring independently of each other is even more unlikely. And because the calculator is not about the full range of possible values but about the values in the 95% confidence interval this leads to the outer edges of the range now falling outside the 95% confidence interval
Really neat idea! However, half of the world has Monday as the first day of the week. A setting to change that would be nice :)
Also there are some holidays missing for Sweden. This is stated in the Swedish Annual Leave Act, which establishes that Midsummer's Eve as well as Christmas Eve and New Year's Eve is to be considered equivalent to a Sunday.
Doesn't work for Sweden anyway, because people will think you're mad if you don't take at least three weeks in July/August, where there are no other public holidays.
Maybe a feature where I'm manually picking some days and it tries to figure out the best way to stretch the remaining nice would be useful.
You can reduce the number of days it places already, though. So if you assume you take 15 days in july just reduce the amount of days by 15. Don't get to visualize them, however, and its choices might overlap with yours, so not a perfect workaround.
I also would like the week to start on a monday, btw. Perhaps it could be tied to the country? When choosing norway, calender could shift to how it's displayed here.
persons = 10~15 // → 10~15
budget = persons * 1~2 // → 12~27
Should it not say 10-30?
