Arithmetic in Date Variables
These variables:
{monthdaynumber}
{monthdaynumberlong}
{yeardaynumber}
{yeardaynumberlong}
{weekdaynumber}
{weekdayname}
{weekdayshort}
{monthnumber}
{monthnumberlong}
{monthname}
{monthshort}
{year}
{yearshort}
{dateshort}
{datelong}
{date}
{datenumber}
{isodate}
also accept a syntax in which days or months can be added to or subtracted from the date, e.g.:
{weekdayname-7d}
is the weekday name seven days ago,
{isodate+2d}
is the date in ISO format two days in the future.
{monthname+3m}
is the name of the month three months ahead,
You can also add or subtract working days, e.g.:
{datelong+5wd}
is the date in five working days.
Note that {datelong+1wd}
is not the next working day, but the date after a working day has passed.
It's a subtle distinction that only matters if the date falls on a weekend: Saturday + 1 working day is Tuesday.
To obtain the next working day, use the following syntax: {datelong+0wd}
. To obtain the previous working day, use the following syntax: {datelong-0wd}
