1 Month From Today
One month from today is a staple deadline for trials, renewals, and short project phases. This shortcut adds one calendar month to today—or any start date—respecting variable month lengths instead of using a thirty-day estimate.

One month from today follows calendar-month rules—January 31 plus one month adjusts to the last valid day in February when needed. Calculate the exact date below.
How this calculator works
The tool adds one month to your start date using true calendar-month arithmetic.
Month-end dates roll forward correctly: adding one month from March 31 lands on April 30.
Today (July 21, 2026) is the default start. Replace it for one-month renewals from a signature or enrollment date.
Worked example
Starting from July 21, 2026, one month ahead is August 21, 2026. A SaaS trial described as "one month from today" should convert or expire on that calendar day.
Enter a lease start date to see when a one-month notice period ends.
Practical use cases
Software free trials and subscription grace periods quoted in calendar months.
Short project milestones and event RSVP windows one month out.
Insurance or warranty follow-ups scheduled one month after a claim filing.
