This document explains the behavior of all date-related filtering options for smart group definitions, including those for calendar dates. Support for calendar dates in smart group selection criteria was introduced in LANrev 4.6.1.

  1. is exactly
    1. Minutes, Hours
    2. Days
    3. Weeks, Months, Years
    4. Calendar Days
    5. Calendar Weeks
    6. Calendar Months
    7. Calendar Years
  2. is in the last 
    1. Minutes, Hours
    2. Days
    3. Weeks, Months, Years
    4. Calendar Days
    5. Calendar Weeks
    6. Calendar Months
    7. Calendar Years
  3. is not in the last
  4. Like "is in the last", but focuses on the inverse range, i.e. any dates not falling in that range, with the exception that only dates that are older than the lower limit of the specified range are included (i.e. the current date and any future dates are never included): e.g. "is not in the last 3 [calendar] weeks" issued today will not include events from today or any future events, even though technically these events are not in the last 3 [calendar] weeks range.

  5. is in the next
    1. Minutes, Hours
    2. Days
    3. Weeks, Months, Years
    4. Calendar Days
    5. Calendar Weeks
    6. Calendar Months
    7. Calendar Years
  6. is not in the next  
  7. Like "is in the last", but focuses on the inverse range, i.e. any dates not falling in that range

  8. is between (The order of the two limiting units doesn't matter, they are always internally reordered to make a non-empty range, i.e. "is between 2 and 3 days ago" is the exact same as "is between 3 and 2 days ago")
    1. Minutes, Hours
    2. Days
    3. Weeks, Months, Years
    4. Calendar Days
    5. Calendar Weeks
