95% attendance is about 9.5 days missed in a 190-day year.
97% attendance is about 5.7 days missed in a 190-day year.
Why these numbers are approximate
Different schools and different parts of the year can use different numbers of possible days or sessions, so these figures are guide numbers rather than exact official totals.
That is why it helps to use your own possible days or sessions in the calculator if you want a closer estimate.
Why sessions are sometimes more accurate than days
Many schools record attendance in sessions, not just whole days. If a child misses one morning or one afternoon, the session total captures that more precisely.
The day-based figures in this guide are still useful for plain-English explanations and quick comparisons.
Reference points

Worked examples
See the attendance maths in context
97% attendance example
184.3 attended days out of 190 possible days = 97%
This usually means a few isolated absences across the year, but even at 97% the total is still more than five school days missed.
90% attendance example
171 attended days out of 190 possible days = 90%
This is a much larger amount of time missed than many people expect when they first hear the percentage.
