== Where does Cumulus get its this month and this year rainfall totals from? ==
* The rainfall totals (for this month, year, and season), are initialised when Cumulus is (re-)started by adding up the corresponding daily totals in [[dayfile.txt]] and storing those sums in memory.
* Each time Cumulus reads records from the weather station it applies any change to the 'total rain count' against today's total in its memory.▼
** The rainfall totals shown on the ''This period'', ''This month'', and ''This year'' screens within the '''View''' menu in Cumulus 1 are generated by adding up the daily rainfall totals found in [[dayfile.txt]] for the selected period.
* The today's total so far at each reading time is also added to the 'recent tag' array allowing total values for the day-so-far at one minute intervals for up to a week ago to be added as web tags to a web template. ▼
▲* Each time Cumulus reads records from the weather station it applies any change to the 'total rain count' against today's total in its memory.
▲* The rainfall totals shown on the ''This period'', ''This month'', and ''This year'' screens within the '''View''' menu are generated by adding up the daily rainfall totals found in [[dayfile.txt]] for the selected period. So any rainfall for the current (meteorological) day is excluded as the latest dayfile.txt row is for yesterday. Totals are recalculated when you press the ''Update display'' button. Important note: The view menu 'This year' screen always calculates the total for a selected calendar year starting in January.
**Today's rain is shown on the front screen in Cumulus 1, labelled ''Today''.

▲** The today's total so far at each reading time is also added to the 'recent tag' array allowing total values for the day-so-far at one minute intervals for up to a week ago to be added as web tags to a web template.
* For the web tags, Cumulus takes its stored sums and adds today's latest total each time, to give the current totals for this month and this rain season (year so far) when processing 'thismonthT.htm' and 'thisyearT.htm' web templates.
**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).
