30 days from today

The date and what lies in between

“Today” is your device’s date, so the answer is right in your time zone. The page itself was generated on the date in the caption; your browser recounts the table when it opens.

How 30 days are counted

Day 1 is tomorrow; day 30 is the answer. Thirty days are 4 full weeks plus 2 days, so the answer always falls 2 days later in the week than today (from a Wednesday, a Friday). Weekends and holidays count as ordinary days; for a deadline in working days, switch the calculator to Business days.

30 days or 1 month?

A month is 28 to 31 days, so “30 days” and “one month” match only in April, June, September and November:

From January 31, 30 days ends on March 2 (or March 1 in a leap year), while 1 month ends on February 28 or 29.

Common 30-day deadlines

• Notices to vacate and lease changes: often 30 days; count from the date the notice is delivered if the lease says so, and enter that date in the date calculator.
• Returns and free trials: a 30-day window usually starts at purchase or sign-up, not today.
• Bills: “due in 30 days” (net 30) counts from the invoice date.
• Short plans: thirty days is a common length for a challenge or a trial; if today counts as day 1, the last day is 29 days from today.

Checking the date by hand

Count whole weeks first, then the days left over: 30 days are 4 weeks and 2 days. On a wall calendar, move 4 rows down from today, then 2 days to the right, wrapping to the next row past the edge. That is quicker and less error-prone than counting single days. The table above also lists the weekdays and the federal holidays you pass, which matters when a deadline has to fall on a business day or an office is closed.

To count the days left until a known date, use days between dates. For longer spans, see 90 days from today; to add up the hours worked in the period, the hours calculator.
