[sm] : Conditional Month Token
Use the token [sm] (and related tokens) if you wish any of the month tokens to appear only on the first of the month ('s' means 'start'). On other days the token converts to a blank. Note that this is not a zap token. Blank means no text.
For example:
•On Thursday June 1st, [sm] = 1, [sMMM] = JUN, [sMmmm] = June.
•On May 3rd, [sm], [sMmm], [smmmm] are all blank.
One way to use the [sm] tokens is in a daily or weekly diary where you want to emphasize the beginning of a new month.
