Date Manager

The Add Time to Date workflow action calculates a new date by adding or subtracting time from an existing date property on a record. Use it to automate renewal dates, follow-up schedules, SLA deadlines, and any other date-based logic.

How It Works

Add the Add Time to Date action to any contact, company, deal, or ticket workflow in HubSpot. When a record reaches this step, the app reads the date you specified, applies the time adjustment, and returns the calculated date for use in later workflow steps.

Action Inputs

When you add the action to a workflow, you will configure the following fields:

Field	Required	Description
Input Date	Yes	The starting date (from a date property or static value)
Years to Add	No	Number of years to add (use negative numbers to subtract)
Months to Add	No	Number of months to add (use negative numbers to subtract)
Weeks to Add	No	Number of weeks to add (use negative numbers to subtract)
Days to Add	No	Number of days to add (use negative numbers to subtract)

You can combine multiple time units in a single action. For example, setting Years to 1 and Days to 30 will add one year and thirty days to the input date.

Action Outputs

After the action runs, the following output values are available for use in subsequent workflow steps:

Output	Type	Description
Result Date (ISO)	Date	The calculated date in standard ISO format, ready to copy into another date property or use in subsequent actions
Result Timestamp	Number	The calculated date as a numeric timestamp, useful when you need to pass the value to other systems
Success	Yes/No	Whether the calculation completed without errors. Use this to branch your workflow and handle failures gracefully.
Error Message	Text	If the calculation failed, this describes what went wrong

Tip: To learn how to use these output values in later workflow actions (e.g., copy to a property, use in branching logic), see Using workflow action outputs in the HubSpot Knowledge Base.

Branching on Results

A common pattern is to add a branch immediately after the Add Time to Date action:

If Success is true - proceed with copying the result date to a property, sending a notification, or continuing your workflow
If Success is false - send an internal alert, skip the step, or route the record for manual review

Usage Examples

Calculate a Contract Renewal Date

Add 1 year to a contract start date to determine when renewal is due.

Input Date: Contract Start Date property
Years to Add: 1

The result date will be exactly one year after the contract started.

Set a Net-30 Payment Due Date

Add 30 days to an invoice date to calculate the payment deadline.

Input Date: Invoice Date property
Days to Add: 30

Schedule a Follow-Up Two Weeks Out

Add 2 weeks to the date of last contact to trigger a follow-up task.

Input Date: Last Contacted property
Weeks to Add: 2

Calculate a Date in the Past

Subtract 90 days from an event date to determine when to start a promotional campaign.

Input Date: Event Date property
Days to Add: -90

Combine Multiple Time Units

Add 1 year and 6 months to a subscription start date to find the mid-point of a multi-year plan.

Input Date: Subscription Start Date property
Years to Add: 1
Months to Add: 6

Tips

Use negative numbers to subtract. Entering -7 in the Days field moves the date one week into the past.
Leave unused fields blank. You do not need to enter 0 for every time unit -- just fill in the ones you need.
Copy the result to a property. After the Add Time to Date action, use a HubSpot "Copy property value" action to save the result date into a date property on the record.
Month-end dates are handled automatically. Adding 1 month to January 31 will give you February 28 (or 29 in a leap year), not an invalid date.
The action works with any date property. Close dates, create dates, custom date properties -- anything HubSpot stores as a date can be used as input.
