This "Count" approach has been chosen because different weather stations output different values, and an independent count is a way of working that can be applied for any weather station. | ||
**As you will see if you look in [[diags]], Cumulus stores the 'total rain count' figure at rollover, so by maintaining the current figure it can subtract off the start of day figure to deduce the rainfall today and this is shown on the front screen in Cumulus 1, labelled ''Today''.

In Cumulus 1 the '''Edit''' menu gives access to the ''Today's rain'' screen and that provides the ability to edit the start of day figure so that the figure shown for today is correct. Equivalent functionality is provided in Cumulus MX. If there is no rain in a day, the start of day count will be the same at the start of the next day. | ||
**Today's rain is added to the figures (as described above) derived from dayfile.txt for what the front screen in Cumulus 1, labels '''This month''', and ''This year'' (this last figure is the seasonal total, you can choose for it to start on 1 January or any other month). Thus these figures are updated each time Cumulus receives a rain reading from the station (they all include today-so-far), and these figures will not be displayed if Cumulus is unable to read rain information from your station. | **Today's rain is added to the figures (as described above) derived from dayfile.txt for what the front screen in Cumulus 1, labels '''This month''', and ''This year'' (this last figure is the seasonal total, you can choose for it to start on 1 January or any other month).

**Important, for the <#ryear> web tag, and for the 'This year' display on the ''main'' Cumulus screen, the processing reads the ''dayfile.txt'' for the rainfall season starting with the month set on the station settings screen and stored as the value for attribute ''RainSeasonStart'' in [[Cumulus.ini#Section:_Station]] (its default is January). | **Important, for the <#ryear> web tag, and for the 'This year' display on the ''main'' Cumulus screen, the processing reads the ''dayfile.txt'' for the rainfall season starting with the month set on the station settings screen and stored as the value for attribute ''RainSeasonStart'' in [[Cumulus.ini#Section:_Station]] (its default is January). | ||
**If you have set a 'year to date' value and Cumulus is being re-started when the year specified beside that figure matches the current calendar year, your year-to-date amount is also added into this year's total. This should normally only be relevant in your first rain season of operating Cumulus, but could be used if in any season you needed to add an extra amount because for some reason you had a gap in your recording period. ''Do be aware that if you select a rain season starting in a month other than January, the year to date figure will stop being added on 1 January because the year specified next to the figure to add on will then be the previous calendar year!'' | **If you have set a 'year to date' value and Cumulus is being re-started when the year specified beside that figure matches the current calendar year, your year-to-date amount is also added into this year's total.
