## Default answer

Example with the default inputs (Count from September 30, 2026) on the example date Wednesday, September 30, 2026: From September 30, 2026, there are 210 days until April 28 on Wednesday, April 28, 2027.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| from | Count from | The date to count from. Today, unless you change it. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| days | Days until April 28 | Whole days from the start date to the next April 28; 0 on the day itself. |
| date | Date | The next April 28 on or after the start date. |
| weekday | Day of the week | The weekday of that date. |
| weeks | In weeks | The same number of days in weeks and days. |

## Method

Find the first April 28 on or after the start date, then count the days from the start date to it.

## Assumptions

- April 28 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before April 28, the count is 1; on April 28 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to April 28, the range the date field accepts.
- Today is the date on your own device, so the count to April 28 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
