Date-based filter conditions

Dates are composed of two elements: date and time. In general, when configuring a filter condition with a date field type, there are two types of conditions you can create: fixed-date and relative-date.

Note:

When specifying a date value with a time component for a filter, enter the time component in your local time zone. The time component will then be converted to coordinated universal time (UTC) behind the scenes before the filter is implemented. After the filter is implemented, the results will be converted from UTC back to your local time zone, which is determined by your web browser settings, before they are displayed in a dashboard element.

Also, to filter features by date, the layer must support standardized SQL functions.

Fixed-date conditions

Fixed-date filter conditions include a specific date value. This value can be entered by choosing a date from the date picker on the Value tab, or by choosing another date field on the Field tab. Choosing a date field works in the same way as entering a specific date value that can update based on data changes to the field.

Options for entering values for fixed date filters
Note:

The Field tab only appears if the element's layer has more than one date field.

A fixed-date filter condition can only be created with the following operators:

  • is
  • is not
  • is before
  • is or is before
  • is after
  • is or is after

Note:

It is possible to create a fixed-date filter condition with a range of fixed dates by creating individual filters with fixed dates and combining them using logical operators.

Relative-date conditions

Relative-date filter conditions include a range of date values. The range can be anchored to or include the current moment in time (that is, now), or it can be a predefined period (for example, last week). The range or anchor type you can enter depends on the operator you choose.

Anchored to now

The benefit of using date ranges anchored to now is that they allow elements to refresh at the rate that data might be changing. For example, an indicator configured to display data that is within the last 30 minutes could potentially show different data every minute if its layer also refreshed that often. However, an indicator that shows data from yesterday will only show different data after today's date has changed (that is, after midnight) regardless of the layer's refresh interval.

When selecting an operator associated with an anchor type of now, you are prompted to specify a unit multiplier (N) as well as a time unit (for example, day, hour, minute, or second). For instance, if the date range is 7 days, the unit multiplier is 7 and the time unit is day.

Date range anchored to now
The following table describes these time units. Note that all date values are in your local time zone.

OperatorTime unitDescription

is within the last

seconds

N seconds before the current second up to now. That is, the range includes this second up until the current time.

minutes

N minutes before the current minute up to now. That is, the range includes this minute up until the current time.

hours

N hours before the current hour up to now. That is, the range includes this hour up until the current time.

days

Starts at 12:00:00 a.m. N days before the current day up to now. That is, the range includes today up until the current time.

is before the last

seconds

Starts at 12:00:00 a.m. N seconds before the current second and continues indefinitely.

minutes

Starts at 12:00:00 a.m. N minutes before the current minute and continues indefinitely.

hours

Starts at 12:00:00 a.m. N hours before the current hour and continues indefinitely.

days

Starts at 12:00:00 a.m. N days before the current day and continues indefinitely.

is within the next

seconds

Starts now and continues N seconds from now. That is, the range includes this second, after the current time.

minutes

Starts now and continues N minutes from now. That is, the range includes this minute, after the current time.

hours

Starts now and continues N hours from now. That is, the range includes this hour, after the current time.

days

Starts now and continues until 11:59:59 p.m. N days from now. That is, the range includes today, after the current time.

is after the next

seconds

Starts at 12:00:00 a.m. N seconds after the current second and continues indefinitely.

minutes

Starts at 12:00:00 a.m. N minutes after the current minute and continues indefinitely.

hours

Starts at 12:00:00 a.m. N hours after the current hour and continues indefinitely.

days

Starts at 12:00:00 a.m. N days after the current day and continues indefinitely.

Anchored to a predefined period

Using date ranges anchored to a predefined period is appropriate when you don't need data to update as frequently as the layer refreshes, which is when you want to use a date range anchored to now.

When selecting an operator associated with a predefined anchor type, you need to specify an interval on the Period tab.

Date range anchored to a predefined period

These periods are based on the following units. Note that start and end times are always based on your local time zone.

  • Day—A day starts at 12:00:00 a.m. and continues for 24 hours, ending at 11:59:59 p.m. In military time, a day starts at 00:00:00 and continues for 24 hours, ending at 23:59:59.
  • Week—A week starts at 12:00:00 a.m. on Sunday and continues for 7 consecutive days, ending at 11:59:59 p.m. on the seventh day, which is Saturday.
  • Month—A month is defined according to the Gregorian calendar. Each month starts at 12:00:00 a.m. (local time) on the first day of the month and continues until 11:59:59 p.m. (local time) on the last day of the month.
  • Quarter—Each year is divided into quarters that are three months long, as described below.
    • 1st quarter—January through March
    • 2nd quarter—April through June
    • 3rd quarter—July through September
    • 4th quarter—October through December
  • Year—A year is the 12-month time period beginning at 12:00:00 a.m. on January 1 and ending at 11:59:59 p.m. on December 31.
