To view the whole daily log use the ''dayfile.txt'' command in '''Edit''' menu. This is how you view, and optionally edit, the dayfile.txt from within Cumulus. If you upload the file to your web site, then see [[AnnualDataSummary]] for information about one of the ways to show values from this file.
==Viewing summary figures for a month or period==
To view a summary of dayfile.txt for a month, calendar year or selected period, use ''This month'' (choose any month, default is month specified in Windows system date), ''This year'' (choose any year, default is year specified in Windows system date), or ''This period'' (choose any start and end dates, default is yesterday calculated from Windows system date), within the '''View''' menu.
Most of the displayed results are for observations in the daily summary log, but a few parameters are not in that log and are derived from the monthly logs (e.g. average wind speed) or the weather diary (e.g. count of days with snow lying).
*Remember the daily summary is based on rollover to rollover days.
*In all cases they exclude the today details that are not stored on dayfile.txt until the end of day rollover.
*If you use 9am or 10am rollover, and choose '''View''' ''This period'' before your 9am/10am rollover your latest meteorological day is the yesterday that 'This period' tries to display as its default day, and the display will appear blank.
*For '''View''' menu, after selecting ''This month'', you can change the month and year required using the options at bottom left, click ''Update Display'' and the revised summary will be calculated.
*For '''View''' menu, after selecting ''This year'', you can change the year required using the options at bottom left, click ''Update Display'' and the revised summary will be calculated.
*For '''View''' menu, after selecting ''This period'', you can change the start date and end date then click ''Update Display'' to get the equivalent calculation for part of a month or any other period.
Note differences between observation reports on View screens and those available as web tags.
*Date and time stamps:
**The day number shown on screen is the meteorological day (changing at rollover and that may be at midnight or 9am/10am) as that date appears in dayfile.txt;
**A time-stamp (with time and date) given in a web tag quotes a calendar date (always changing at midnight).
*Reported statistics example:
**The screen shows total number of dry or wet days in the month;
**The web tags report longest dry or wet period in the month.
