Sunrise & Sunset in Google SheetsSunrise & Sunset in Google Sheets

OnlineCredit Usage:1 per cell

Formula

Get solar times by the row. =VERVE("sunrisesunset", A2, B2) returns sunrise and sunset for a lat/lon — Google Sheets or Excel.

In a cell
=VERVE("sunrisesunset", A2, B2)
In a cell
=VERVE.CALL("sunrisesunset", A2, B2)

A2 holds lat, B2 holds lon. Arguments go in that order — the same order as the table below.

With literal values

Nothing has to come from a cell — typed values work the same way.

Sheets
=VERVE("sunrisesunset", 36.72016, -4.42034)

Inputs

Required inputs are positional, in the order below. Everything else is passed as a "name", value pair after them — the same shape as SUMIFS.

InputTypeWhere it goesDescription
latRequirednumberargument 2The latitude of the location (e.g. 36.72016)
lonRequirednumberargument 3The longitude of the location (e.g. -4.42034)
datePremiumstring"date", valueThe date for which you want to get the sunrise and sunset times (e.g., MM-DD-YYYY : 01-01-2022) (e.g. 01-16-2026)

Passing an option

Sheets
=VERVE("sunrisesunset", A2, B2, "date", "01-16-2026")

What lands in your sheet

With no "field" pair the formula spills the whole response as two columns — field name on the left, value on the right — starting at the cell you typed in. Make sure the cells below and to the right are empty.

Pulling one value

Add a "field" pair to get a single cell back instead of a table. The field name is the dot-path from the table below.

Returns sunrise
=VERVE("sunrisesunset", A2, B2, "field", "sunrise")
Returns sunrise
=VERVE.CALL("sunrisesunset", A2, B2, "field", "sunrise")

Available fields

Fields marked Premium need a paid plan. On the free plan those cells read #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

Filling a whole column

Hand the first argument a range instead of a cell and the add-in makes one batched call for the lot, then spills the answers down. That is faster than dragging the formula and costs the same credits — one per row looked up.

Rows 2–100 in one call
=VERVE("sunrisesunset", A2:A100, B2, "field", "sunrise")
Rows 2–100 in one call
=VERVE.CALL("sunrisesunset", A2:A100, B2, "field", "sunrise")

A2:A100 is the column of lat values. The result spills down alongside it, one row per input, blanks skipped.

When a cell doesn't fill

A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() won't catch it; test with LEFT(cell, 4) = "#ERR" instead.

Cell readsWhat happened
#ERR Not connectedNo API key saved. Open the side panel and connect your account.
#ERR Replace <name> with a cell or valueThe preview formula was copied as-is. Swap the placeholder for a cell reference.
#ERR No "x" in sunrisesunsetAn option name that this source doesn't take. The message lists the ones it does.
#ERR No data point "…"The "field" path isn't in the response. Check the dot-path against the table above.
#PREMIUM(field)The field exists but your plan doesn't include it.
#ERR Out of creditsThe month's credits are spent. Usage resets on your billing date.

Before the formula works

The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet doesn't leak it and a collaborator without access simply sees the last calculated values.

  1. Install the add-in for Google Sheets or Excel.
  2. Open the side panel and sign in, or paste a key from your dashboard.
  3. Type the formula above into any cell.

Frequently asked questions

Does Sunrise & Sunset in Google Sheets work in both Google Sheets and Excel?

Yes — the same source, the same arguments. Sheets calls it =VERVE("sunrisesunset", …) and Excel calls it =VERVE.CALL("sunrisesunset", …); that function name is the only difference.

Do the cells recalculate on their own?

They recalculate when the sheet does — on edit, on open, or on a manual recalc. Each recalculation is a fresh call and spends credits, so for a large static column it's worth copying the results and pasting them as values.

How many credits does a filled column cost?

1 credit per row looked up, whether you drag the formula or pass a range. The range form is one HTTP call instead of many, but the credit count is the same.

Can I share the sheet without sharing my key?

Yes. The key is stored against your account, not in the file. Collaborators see the values already in the cells; formulas only recalculate for someone who has connected their own account.

Why is a cell showing #ERR instead of an error?

So you can read the reason. Excel can't display a custom message on a real spreadsheet error, so the add-in returns the explanation as text on both platforms instead.
