What is Gravity Perks Gravity Forms Date Time Calculator?
Gravity Perks Date Time Calculator is a Gravity Forms addon that enables date and time arithmetic within form fields, calculating differences between dates, adding or subtracting time intervals, computing business day counts excluding weekends and holidays, and integrating results with Gravity Forms calculation fields for pricing and scheduling applications.
Key Features
Date Difference Calculation
Compute intervals between two date fields in days, weeks, months, years, hours, or minutes.
Business Day Counting
Calculate working days excluding weekends and user-configured holidays from date ranges.
Date Addition/Subtraction
Add or subtract specified intervals from base dates to compute future or past dates.
Time Interval Math
Calculate hours and minutes between time field values for scheduling and duration forms.
Calculation Field Integration
Feed date calculation results into Gravity Forms pricing and calculation fields for formulas.
Configurable Output Formats
Display results as numeric values, formatted date strings, or custom patterns matching form context.
Who is this for?
Pros
- Business day calculations account for weekends and configurable holiday exclusions
- Results integrate with Gravity Forms calculation fields for date-based pricing formulas
- Multiple output units (days, weeks, months, hours) provide flexibility for different use cases
- No custom code required for complex date arithmetic within form calculations
- Configurable result formatting matches output to the specific form context
Cons
- •Requires both Gravity Forms and Gravity Perks licenses as prerequisites
- •Complex multi-step date calculations can be difficult to configure and debug
Product Description
Gravity Perks Date Time Calculator adds date and time calculation capabilities to Gravity Forms fields. It performs arithmetic operations on date and time values — calculating durations between dates, adding intervals, computing business days, and formatting results — directly within form calculations without custom code.
Date Difference Calculations
Calculate the time between two dates in various units: days, weeks, months, years, hours, or minutes. This is useful for rental duration forms, age calculations, project timeline estimates, and any scenario where the difference between two dates determines a value.
Calculation Types
- Date differences — compute the interval between two date fields in configurable units
- Date addition/subtraction — add or subtract days, weeks, or months from a base date
- Business day calculations — count only working days, excluding weekends and configurable holidays
- Time interval math — calculate hours and minutes between time field values
Integration with Gravity Forms Calculations
Date Time Calculator results feed into Gravity Forms' standard calculation fields. This means you can use date durations in pricing formulas — for example, multiplying a daily rate by the number of rental days to compute total costs directly on the form.
Format Control
Configure how calculation results display to users. Choose between numeric values, formatted date strings, or custom output patterns. This flexibility ensures results match the context of your form's purpose and the expectations of form users.
