How to Include Date Ranges in Dataview Queries in Obsidian

Dataview is a powerful tool for working with your notes in Obsidian, allowing you to query and manipulate your data in a flexible and efficient way. One of the most common requirements is to filter data based on dates, and in this article, we'll explore how to include date ranges in your Dataview queries.

Understanding Date Fields in Dataview

Dataview uses the YAML frontmatter of your notes to access date information. To include a date in your notes, you need to create a YAML frontmatter entry with a specific key and assign it a date value. For instance:

---
date: 2023-09-28
---

This code snippet creates a "date" field in your note's frontmatter and assigns it the date "2023-09-28". You can use different keys for your date field, as long as you consistently use the same key for all your notes.

Filtering Notes Within a Date Range

To filter notes within a specific date range, you can use Dataview's built-in date functions. Here's how:

1. Using the date Function:

The date function allows you to filter notes based on the date field in your frontmatter. Here's an example:

LIST
WHERE date >= 2023-09-01 AND date <= 2023-09-30

This query will list all notes where the "date" field falls between September 1st and September 30th, 2023.

2. Using the between Function:

The between function provides a more concise way to define date ranges. Here's how you can rewrite the previous query using between:

LIST
WHERE date BETWEEN 2023-09-01 AND 2023-09-30

3. Using the start and end Properties:

You can use start and end properties for more complex date range filtering. Let's assume you have a field called "eventDate" in your frontmatter. You can filter based on the event duration like this:

LIST
WHERE eventDate.start >= 2023-09-01 AND eventDate.end <= 2023-09-30

This query will list all notes where the "eventDate" falls completely within the range of September 1st and September 30th, 2023.

Tips for Working with Date Ranges in Dataview:

  • Date Formats: Dataview uses the ISO 8601 date format (YYYY-MM-DD). Ensure your date values in the frontmatter adhere to this format.
  • Combining Date Range Filters: You can combine different date range filters to create more complex queries. For example, you could filter notes based on a date range and a specific tag.
  • Customizing Date Ranges: Use relative date ranges by combining the date function with operators like <, >, <=, and >=. For example, date < 2023-10-01 will select notes with a date before October 1st, 2023.

Examples of Practical Applications:

  • Listing Notes for a Specific Month:

    LIST
WHERE date >= 2023-10-01 AND date < 2023-11-01

  • Finding Projects with Deadlines in the Next Week:

    LIST
WHERE deadline >= date(now) AND deadline <= date(now + 7 days)

  • Listing All Notes Created in the Past Year:

    LIST
WHERE date >= date(now - 1 year) AND date <= date(now)

Conclusion

Including date ranges in your Dataview queries provides a powerful way to organize and filter your notes based on time. Mastering these techniques allows you to unlock new levels of efficiency and insights from your Obsidian notes.
