5 months until Daylight Saving Time starts
Counting whole calendar months, there are 5 months and 19 days until Daylight Saving Time starts on Sunday, March 14, 2027. Today is September 23, 2026, so the span runs from September through to March.
How many months until Daylight Saving Time starts?
5 months and 19 days. The count steps the month number forward from September 23, 2026 while keeping the day of the month fixed, which is what a calendar month actually is. After 5 steps the date reaches February 23, 2027, and 19 further days are needed to land on March 14. Clocks go forward one hour at 2am local time on the second Sunday of March in most of the United States, so that night is 23 hours long.
Why month counts disagree with each other
A month is the one unit on the calendar with no fixed length. Calendar counting gives 5. Dividing 172 days by the average month of 30.436875 days gives 5.65, and dividing by a flat 30 gives 5.73. All three are defensible, and they differ because February runs to 28 days while March runs to 31. The headline figure here is the calendar one, because that is what people mean when they say they have 5 months to get ready.
The months between now and Daylight Saving Time starts
| Month | Days in month | Notes |
|---|---|---|
| September 2026 | 30 | in progress today |
| October 2026 | 31 | a full month ahead |
| November 2026 | 30 | a full month ahead |
| December 2026 | 31 | a full month ahead |
| January 2027 | 31 | a full month ahead |
| February 2027 | 28 | a full month ahead |
| March 2027 | 31 | contains Daylight Saving Time starts |
The span crosses 7 named months, which is not the same as 5 whole months: the first and last are only partly inside it. Their real lengths are what pull the average figure of 5.65 away from the whole-number answer.
