st: How to define shortest possible period with 95% of observations

Hi there.
I have a strongly unbalanced panel with 100,000 observations (=fire
occurrences per day) that contain between none (no fire) and 3,000 fires
per day for 8 years. The fire events peak in March and April with about
85-90% of the yearly total.
My question is how I can define the shortest possible continuous period
of days for each year that contains 95% of all yearly fires. The length
and width of the periods may slightly differ across the years due to
climate and other parameters.
I am sure there is a neat trick in Stata for this, yet I have not
spotted it. Any suggestions would be appreciated.
Thank you in advance and best regards,
Daniel
