Add To A Date

Move a date forward by a number of years, months, days, hours or other units.

What it does

Add To A Date takes Date to add to, adds Duration of the chosen Time unit to add, and writes the new date into a field named by Output field name.

• Units: year, quarter (3 months), month, week (7 days), day, hour, minute, second.
• The calculation uses your computer’s local time zone, so adding 1 day keeps the same clock time even across a daylight-saving change.
• A negative Duration moves the date back, but Subtract From A Date reads more clearly.
• Adding a month to the 31st rolls over when the next month is shorter: January 31 plus 1 month gives March 2 or 3.

When to use it

• Work out a due date, for example 14 days after an order date.
• Set an expiry time, such as “now plus 1 hour”.
• Build the end of a date range to send to an API.

Date to add to accepts a date you pick, or an expression such as {{ $input.createdAt }}. ISO dates (2026-03-01, 2026-03-01T09:30:00Z) are the safest format.

Outputs

• Output

The item holds one field, named by Output field name, with the new date. Turn on Include input fields to keep the incoming fields next to it, for example { dueDate, orderId, customer }.

Dependencies and credentials

None. This node needs no connection and has no slots for other nodes.

Example workflow

Remind yourself of a follow-up one week from today:

1. Get Current Date, Output field name now.
2. Add To A Date, Date to add to {{ $input.now }}, Time unit to add week, Duration 1, Output field name followUp.
3. Format Date, Date to format {{ $input.followUp }}, Format DD/MM/YYYY.
4. Browser Notification showing the formatted date.

Common issues

• The output is “Invalid Date” or empty. The incoming value is not a date the browser understands. Use an ISO date such as 2026-03-01, or reshape it first.
• The result is off by a few hours. The date was read in a different time zone than you expected. Include the time zone in the input (Z or +02:00).
• The new date is missing after the node. With Include input fields on, an incoming field with the same name as Output field name replaces the result. Pick a name the input does not already use.

Related nodes

• Subtract From A Date: move a date back.
• Round a Date: snap the result to the start or end of a day, month or year.
• Format Date: turn the result into readable text.
• Get Time Between Dates: compare two dates.
