Why it isn’t exactly 26
26 weeks is 182 days. A real 6-month stretch is shorter when it includes February (for example January 1 to July 1 is 181 days) and longer when it covers July and August, which are both 31 days (for example July 1 to January 1 is 184 days). So “6 months” and “26 weeks” can land up to two days apart.
Worked example
From October 30, 2026, six months later is April 30, 2027. That is 182 days, exactly 26 weeks. The calculator above counts it for you; change the dates to match your own start.
Where the difference matters
Contracts, leases, probation periods and medical guidance usually say which they mean. If a rule says “26 weeks”, count 182 days; if it says “6 months”, go to the same date six months later. Benefit rules and employment law in particular often use weeks, so check the wording.
