Menstrual Cycle Calculator in Google Sheets & Excel — =VERVE("menstrualcycle", "2024-01-01")

What this pulls

Predict cycles from a cell. =VERVE("menstrualcycle", A2) returns period, ovulation and fertile-window dates — Google Sheets or Excel.

It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 1 credit per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.

Ways to use it

One value per row

Fill =VERVE("menstrualcycle", "2024-01-01") down a column and Menstrual Cycle Calculator returns a result for every row — a batch of live values in a single drag, no code.

Enrich data in place

Add Menstrual Cycle Calculator beside a table you already have to append its output right where your data lives, then sort, filter, or chart on it.

Stays fresh on its own

Set the sheet to refresh on a schedule and the menstrual cycle calculator values keep themselves current without anyone re-typing.

Use it in your sheet

The same function works in both apps — install once, sign in with your key, and type it into any cell.

Google SheetsAdd-on

Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.

=VERVE("menstrualcycle", "2024-01-01")

Microsoft ExcelAdd-in

Same source, same arguments, same key — in Excel on desktop, the web, or mobile. Excel namespaces it as VERVE.CALL. Drag to fill a whole column.

=VERVE.CALL("menstrualcycle", "2024-01-01")

Optional inputs

Tune the result by adding name=value before the field argument — in any order. Leave one out and its default applies.

Menstrual Cycle Calculator, answered

Everything you need to wire it into a sheet.

How do I pull Menstrual Cycle Calculator into a spreadsheet?

Install the VerveSheets add-on, sign in with your key, and type =VERVE("menstrualcycle", "2024-01-01") into any cell. The same function works in Google Sheets and Excel — no scripts, no API wiring.

How many credits does each Menstrual Cycle Calculator cell cost?

Each resolved cell costs 1 credit. Filling a column of ten rows costs ten times that; a cell only re-bills when it actually refreshes, so a static sheet doesn't keep charging.

Can I fill a whole column at once?

Yes. Reference a range instead of a single cell — e.g. point Menstrual Cycle Calculator at A2:A50 — and it returns a value for every row in one call, or just drag =VERVE("menstrualcycle", "2024-01-01") down like any spreadsheet function.

Does Menstrual Cycle Calculator work in Excel as well as Google Sheets?

Yes. It's the same =VERVE() function with the same arguments and the same key in both — build a sheet in one and it behaves identically in the other.

How current is the data?

Menstrual Cycle Calculator is served live from APIVerve's production data engine, and cells recalculate on the refresh cadence you choose — every open, hourly, or every 30 minutes.

Where does the data come from, and what shows on my bill?

VerveSheets runs on APIVerve, our production data engine; Menstrual Cycle Calculator is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
