# SECOND Function – Google Sheets

The SECOND function is a simple date function that returns the number of seconds from a given time. If you are working with times but only care about the seconds, the SECOND function lets you eliminate everything else.

Remember that dates are just saved as numbers by your spreadsheet with date formatting applied.

This function is rarely used on its own. Typically, it is nested inside other functions, such as TIME.

## Purpose

The SECOND function returns the number of seconds from any given unit of time.

## Syntax

`=SECOND(time)`

## Common Errors

#VALUE! – The value passed to the function was not a valid time.

#ERROR! – Formula parse error. The input to the function could not be used, such as a time with no quotes. – `5pm` should be `"5pm"`.

#NUM! – The result was not a number, or the number is too large to resolve to a time.

The output is an unexpected format, such as 12:00 AM. – This means the formatting is incorrect, not the underlying number.

Calculate any duration in:

• Years
• Months
• Weeks
• Days
• Hours
• Minutes
• Seconds
• Milliseconds

## Examples

### Example 1 – Stand-Alone SECOND Functions

Following are a few simple examples.

### Example 2 – Separating the Values of a Date and Time

Different date values examined using various functions.

• 1 A random date typed in using slashes.
• 2 A random date typed in using dashes. Note that it is processed the same way as the date with slashes.
• 3 Typed a random date in and added a time. Now the function extracts the hours and minutes.
• 4 Typed in a date but spelled out. Writing out the date also works, but it won’t work if you write the day as “31st” instead of 31.
• 5 If you only type in a time, the “zero” date is 12/30/1899.
• 6 Entered with the NOW function. The output will constantly change in the linked Google Sheet.
• 7 Entered with the TODAY function. The output will change daily in the linked Google Sheet.
• 8 A blank cell is December 30, 1899. Similar to tickmark 5.
• 9 Typing a 1 will increment the value in number 10 above by 1 day. In other words, “1=12/31/1899”. It is just a matter of how it is displayed, which can be controlled by going to the Format menu and choosing Number.
• 10 Just a decimal with no whole number increments the value by hours, minutes, and seconds instead of days.
• 11 To get near the current date, you need to start with 43,000 days away from 12/30/1899.
