How to use this calculator
Enter the term start, inclusive term end and date to look up. Select the first weekday, add break ranges and choose whether numbering continues through breaks.
Week 1 contains the term's starting date. Pausing requires a complete aligned seven-day break, including weekend dates. Partial breaks keep their week number. Dates outside the term and dates inside breaks are labeled explicitly.
A worked example
For a Monday-start term beginning September 7, 2026, November 2 is calendar week 9. Pausing the complete October 26–November 1 break makes it academic week 8.
Is an academic week the same as an ISO week?
No. Academic numbering starts at your term; ISO numbering follows an international week-year. Institutions can count reading weeks differently, so enter your institution's rule.

Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results inside that range. Most daily plans are limited to 366 dates; academic terms and sprint plans allow up to 731. Forms limit the number of entries to keep calculations responsive. Holidays and policy rules come from your inputs. Date-only plans ignore DST; tools with time-zone inputs use the browser's time-zone data and explicitly resolve repeated times. Calendar exports preserve date-only markers or exact timed events as appropriate. Calculations run only when requested, without background polling.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
