A major milestone: babies born from this week have a chance of survival with intensive care. The lungs are starting to make surfactant, and the glucose screening test is usually scheduled between now and 28 weeks.

The inner ear is fully developed, giving the fetus a sense of balance and awareness of being upside down or right way up. Taste buds are functional, and the brain is growing rapidly. Fat deposits are just beginning to smooth out the wrinkled skin, and the face is fully formed with lashes, brows and hair.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Your uterus is now the size of a soccer ball and rises above your navel. Lower belly and back aches can be more persistent, and clumsiness is a real thing as your center of gravity shifts. Blurred vision or dry eyes may occur due to fluid changes and usually resolve after birth.

At 24 weeks 0 days you are 168 days into a 280-day pregnancy, which leaves 112 days — 16 weeks — until 40 weeks. That number drops by one for every day you move through this week. Remember the due date is an estimate: only about 1 in 20 babies is born on it, and most arrive within two weeks on either side.
Next milestone: 28 days until the third trimester (28 weeks 0 days).
A calendar month averages about 4.3 weeks — not 4 — so you can't just divide your week number by four. Instead, months of pregnancy are counted as uneven buckets of 4 to 5 weeks, arranged so the full 40 weeks fits into 9 calendar months. Week 24 falls in month 6, in the second trimester.
Your care team will always use weeks and days rather than months, because screening windows and term definitions are set by exact week — months are just the everyday shorthand. For the full conversion, see the weeks to months chart, or go the other way with the months-to-weeks guide.
Your notes will show a week and a day — 24+3 or 24w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.
| Week + day | Shorthand | Days pregnant | Days to go |

| 24 weeks 0 days (this page) | 24+0 | 168 | 112 |
| 24 weeks 1 day | 24+1 | 169 | 111 |
| 24 weeks 2 days | 24+2 | 170 | 110 |
| 24 weeks 3 days | 24+3 | 171 | 109 |
| 24 weeks 4 days | 24+4 | 172 | 108 |

At 24 weeks pregnant, you are about 6 months pregnant — in month 6 of your pregnancy and in your second trimester. Months of pregnancy are counted as uneven 4–5 week buckets so that the full 40 weeks fits into 9 calendar months.
24 weeks is in the second trimester, which runs from 14 weeks 0 days through 27 weeks 6 days. The third trimester begins at 28 weeks 0 days.
About 16 weeks until the 40-week mark — though only about 1 in 20 babies arrives exactly on the due date. Most are born within two weeks on either side of it.
At 24 weeks 0 days you are 168 days into a 280-day pregnancy, so there are 112 days left until the 40-week mark — that's 16 weeks. The count drops by one for each day you move through week 24.
24 weeks is 168 days, counted from the first day of your last menstrual period (24 × 7 = 168). Add the days into your current week for the exact figure — for example 24 weeks 3 days is 171 days.
