DatePlus

DatePlus
gives the date n days after date.
DatePlus
gives the date n units after date.
DatePlus
gives a date offset by units of each specified size.
DatePlus[n]
gives the date n days after the current date.
DatePlus[offset]
gives the date with the specified offset from the current date.
  • DatePlus gives the date n days before date.
  • Dates can be specified in the following forms:
{y,m,d}year, month, day
{y,m}the first day of the specified month
{y}January 1 of the year y
"string"date as a string ()
{y,m,d,h,m,s}precise time
timeabsolute time specification
  • Possible offset units are , , , , , , , .
  • is taken to be equivalent to , etc.
  • DatePlus gives results in the same general format as date.
  • When date is a list, the result has the same length as date, possibly extended to include the smallest unit in offset. »
