I need help with date search! How do I do X?

It depends on what you want to find, the context of the search (which part of the graph it is made in), and the time scale/granularity you are looking for.

Below are possible queries you can use to find date-related things in Tana. A quick legend:
> : Typing this key starts a field anywhere in Tana, so we prefix fields with this sign when writing out queries in text

LT/GT : Less than/Greater than field operators

text : Text in this style is meant to be written out

I want to find all overdue items from a deadline date field...

• based on what the time is right now (most efficient graph-wise):
  • >LT : >your deadline field : FOR RELATIVE DATE today
  • Example: You are making a task dashboard in the tree that is always showing you information based on the current time
• based on the date in a date field of parent node:
  • >LT : >your deadline field : PARENT.date field
  • Example: You can see overdue tasks based on the date of the meeting note
• based on the date of an ancestor calendar node:
  • >LT : >your deadline field : PARENT/GRANDPARENT
  • Example: You have a search node as part of your #day supertag template

I want to find deadline dates that fall within a range (let's say, a week)...

• based on what the time is right now, and this/last/next week/month/year:
  • >your deadline field : FOR RELATIVE DATE this/last/next week
• relative to a date field of the parent node:
  • >LT : >your deadline field : PARENT.date field
  • >GT : >your deadline field : PARENT.date field-7
• relative to the date of a calendar node:
  • >LT : >your deadline field : PARENT
  • >GT : >your deadline field : PARENT-7

I want to find nodes based on their location in the journal nodes...

• To pick up the date based on the calendar node they are nested under, use system field Date from calendar node
• For field value, use any variation from the above examples depending on need and context

I want to find nodes relative to the search node's location in a journal node...

• Relative to parent
  • PARENTS DESCENDANTS
  • Example: A search node on a day page limits search to only nodes that live on the parent Day page
• Relative to grandparent
  • GRANDPARENTS DESCENDANTS
  • Example: A search node on the day page limits search to only nodes that live on the grandparent Week page
• For both operators, add WITH REFS to include references in the search

I want to find nodes based on when they were created/edited/done relative to now (replace X with a number)

• CREATED LAST X DAYS
• EDITED LAST X DAYS
• DONE LAST X DAYS

I want to find nodes based on when they were created/edited/done relative to a date field of the parent node

• Use system fields Created time, Last edited time, and Done time
• As field value, write out PARENT.date field
