Why date calculators give different answers
What is January 31 + 1 month?
February 28, 2027: we stop at the last day of the month. Some tools roll over to March 3 instead.
90 days, 13 weeks or 3 months?
From October 31, 2026: 90 days → Fri, Jan 29, 2027 · 13 weeks → Sat, Jan 30, 2027 · 3 months → Sun, Jan 31, 2027.
Every result follows the rules on How we calculate. Before every release, automated tests compare 20,000 random dates with the date functions built into JavaScript and check that month and business-day results add up.
