30 Days Ago? Countdown
30 days ago is today’s civil date minus 30 calendar days in the timezone you pick. The date at the top is that morning in your timezone, then midnight of the same count in other cities.

30 days ago
Thirty days ago is last month as a 30-day block. People ask for the date they stood on a month back: a purchase, a photo, a notice that started a 30-day clock. Subtract 30 civil dates from today in the timezone you pick.
“30 days before today” and “30 days prior to today” are the same count. They are not “the same numbered day last month,” which can be 28–31 days.
A month back, as 30 dates
Looking backward still hits the date line. If it is already tomorrow in Sydney, their 30 days ago is one square later than Honolulu’s. The city list at the top is that gap. The large date above the article is the result in your zone. “30 days ago from today”, “what was 30 days ago”, “what was the date 30 days ago”, “what day was 30 days ago”, “what day was it 30 days ago”, “30 days ago today”, “date 30 days ago”, “what date was 30 days ago”, and “when was 30 days ago” are the same 30 days ago.
Why this countdown exists
30 days ago is a look-back search. The answer is a past civil date, so this page prints that date instead of counting down to a finished morning.
Questions people ask
Is this the same as last month?
Not always. Last month’s same numbered day varies. This page subtracts 30 dates.
Before today vs ago?
Same math on this page: 30 civil days earlier than today.
Why other countries?
Their “today” may already differ, so their 30 days ago differs too.
