Extract Part Of A Date

Pull one number out of a date, such as its year, day of the month or hour.

What it does

Extract Part Of A Date reads Date to extract part from and returns one number, chosen with Part of date to extract, in the field named by Output field name. Values are read in your computer’s local time zone.

Part	What you get
year	The full year, for example 2026.
month	The month counted from 0: January is 0, December is 11.
week	The day of the month divided by 7, a decimal (the 15th gives about 2.14). It is not a week-of-year number.
day	The day of the month, 1 to 31.
hour	0 to 23.
minute, second	0 to 59.

When to use it

• Branch on the hour, for example only notify between 9 and 18 with IF.
• Group or label items by year.
• Check whether today is the 1st of the month.

To turn a date into readable text, use Format Date instead.

Date to extract part from accepts a picked date or an expression such as {{ $input.publishedAt }}. ISO dates (2026-03-01T09:30:00Z) work best.

Outputs

• Output

The item holds one number under Output field name, for example { hour: 14 }. Turn on Include input fields to keep the incoming fields too.

Dependencies and credentials

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

Example workflow

Only send a notification during working hours:

1. Get Current Date, Output field name now.
2. Extract Part Of A Date, Date to extract part from {{ $input.now }}, Part of date to extract hour, Output field name hour.
3. IF: {{ $input.hour }} is greater than or equal to 9 and less than 18.
4. On the true branch, a Browser Notification.

Common issues

• The month is one lower than expected. Months start at 0. Add 1 with Math, or use Format Date if you need it as text.
• “week” returns a decimal. It is the day of the month divided by 7, not the week of the year.
• The output is empty or NaN. The incoming value is not a date the browser can read. Use an ISO date such as 2026-03-01.

Related nodes

• Format Date: turn a date into text.
• Round a Date: snap a date to the start or end of a unit.
• IF: branch on the extracted number.
