About Term Dates Calculator

A fourteen week term with a one week half-term break spans fifteen calendar weeks and delivers 70 teaching days. Starting 7 September 2026, the half-term break falls in mid-October and the term ends in mid-December. Splitting the term at the midpoint is the usual convention, though many schools shift it to align with public holidays.

Formulas

Teaching days

days = term weeks x 5

Term end

end = start + (term weeks + break weeks) x 7 days

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why place the break at the midpoint?

To divide the term evenly, though in practice it is usually aligned to the last week of October or February for consistency across a region.

Are inset days included?

No. Staff training days reduce pupil teaching days, so subtract them separately from the figure here.
