Date & Time Operators

Date operators let you compare dates, check if something is recent, and validate ages.

Later Than

Check if a date is after another date:

__expiry__ of **License** is later than date(2024-01-01)

Interactive Example

Reset

Policy Rule

A **License** is valid if __expiry__ of **License** is later than date(2024-01-01).

Test Data (JSON)

{ "License": { "expiry": "2025-06-15" } }

▶ Run

Earlier Than

Check if a date is before another date:

__created__ of **Account** is earlier than date(2020-01-01)

Interactive Example

Reset

Policy Rule

Test Data (JSON)

{ "Account": { "created": "2018-03-22" } }

▶ Run

Within (Recency)

Check if a date is within a duration from now:

__last_login__ of **User** is within 30 days
__test_date__ of **Driver** is within 2 years

Supported time units: seconds, minutes, hours, days, weeks, months, years, decades, centuries.

Interactive Example

Reset

Policy Rule

A **User** is recently active if __last_login__ of **User** is within 7 days.

Test Data (JSON)

{ "User": { "last_login": "2026-03-28" } }

▶ Run

Older Than

Check if a date-based age exceeds a duration. Useful for age verification:

__date_of_birth__ of **Person** is older than 18 years

Interactive Example

Reset

Policy Rule

A **Person** is adult if __date_of_birth__ of **Person** is older than 18 years.

Test Data (JSON)

{ "Person": { "date_of_birth": "2000-01-15" } }

▶ Run

Younger Than

The inverse of older than:

__date_of_birth__ of **Person** is younger than 65 years

Interactive Example

Reset

Policy Rule

A **Person** is working age if __date_of_birth__ of **Person** is older than 18 years and __date_of_birth__ of **Person** is younger than 65 years.

▶ Run

Comparing Against Another Property

All duration operators (within, older than, younger than) can compare against another date property instead of the current date by adding of followed by a property access:

<property> is <operator> <duration> of [the] <property>

Within … of

Check if two dates fall within a duration of each other:

the __date__ of the **theory** in the **testDates** in the **drivingTest** is within 2 years of the __date__ of the **practical** in the **testDates** in the **drivingTest**

Interactive Example

Reset

Policy Rule

A **drivingTest** is valid if the __date__ of the **theory** in the **testDates** in the **drivingTest** is within 2 years of the __date__ of the **practical** in the **testDates** in the **drivingTest**.

Test Data (JSON)

{ "drivingTest": { "testDates": { "theory": { "date": "2024-03-15" }, "practical": { "date": "2025-06-20" } } } }

▶ Run

When the dates are too far apart, the condition fails:

Interactive Example

Reset

Policy Rule

A **drivingTest** is valid if the __date__ of the **theory** in the **testDates** in the **drivingTest** is within 2 years of the __date__ of the **practical** in the **testDates** in the **drivingTest**.

Test Data (JSON)

{ "drivingTest": { "testDates": { "theory": { "date": "2022-01-10" }, "practical": { "date": "2025-06-20" } } } }

▶ Run

Older Than … of

Check if one date is older than a duration relative to another date:

Younger Than … of

Check if one date is younger than a duration relative to another date:

__renewal__ of **Policy** is younger than 6 months of __expiry__ of **Policy**
