Example with the default inputs (Count from October 19, 2026) on the example date Monday, October 19, 2026: From October 19, 2026, there are 294 days until the first day of school, Monday, August 9, 2027.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| from | Count from | The date to count from. Today, unless you change it. It is not counted. |
| first | First day of school | Your school’s first day, from its calendar. Left empty, the page counts to an example: the next first day of school of Northside ISD, San Antonio, Texas. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| days | Days until school starts | Calendar days from the start date to the first day of school; 0 on the first day itself. |
| weeks | In weeks | The calendar days as whole weeks and days. |
| date | First day of school | The first day of school counted to. |
| example | Example calendar | The district calendar the first day comes from, when the box is left empty. |

## Method

days = first day of school − start date, in calendar days; weeks = days ÷ 7 rounded down, with the days left.

## Assumptions

- The start date is not counted and the first day of school is: from the day before, the count is 1; on the first day, it is 0.
- With the first day left empty, the page counts to the first first day of school on or after the start date in Northside ISD’s published calendars (San Antonio, Texas): August 10, 2026 (2026–27) or August 9, 2027 (2027–28), and names the school year. After August 9, 2027, enter a date.
- A first day of school before the start date has no answer.
- Dates from January 1, 2000 to December 31, 2100 work. Dates are calendar days with no time of day.

## FAQ

### How many days until school starts?

It depends on your school, because each district sets its own calendar. Enter your school’s first day and the page counts from today. As an example, Northside ISD in San Antonio, Texas starts its 2027–28 school year on Monday, August 9, 2027: from Monday, October 19, 2026 that is 294 days, exactly 42 weeks.

### Is today counted?

No. The count starts after the start date and includes the first day of school, as a “days until” count does. On the first day the count is 0; the day before, it is 1.

### Why does the page show Northside ISD’s date?

Only as an example of a published calendar, used when the first day is left empty. Northside ISD publishes its calendars two school years ahead: its school years start on August 10, 2026 and August 9, 2027. After August 9, 2027 the page asks for your date until the next calendar is added.

### When does school start in the US?

It depends on the district. Northside ISD in Texas started its 2026–27 year on Monday, August 10, 2026, and New York City public schools on Thursday, September 10, 2026, a month later. Check your district’s calendar.

### How many weeks until school starts?

The page shows the days as whole weeks and the days left. 69 days, from June 1 to August 9, 2027, is 9 weeks and 6 days.

### Where do I find my first day of school?

On your school district’s calendar page. Districts publish their own dates: Northside ISD, for example, approved its 2026–27 and 2027–28 calendars together in December 2025.
