Asq Calculator

YYYY-MM-DD. Required in every mode except the reverse mode, which works it out for you.
Leave blank to use today. Set it to any past or future date to age forward or backward.
ASQ mode: completed weeks of gestation at birth. 40 weeks is full term.
ASQ mode: the days part of the gestational age, e.g. 32 weeks 4 days.
ASQ mode: if you know the due date, it is used instead of the gestational age.

How this is worked out

7 steps
  1. Weeks premature = 40 weeks (280 days) - gestational age at birth = 56 day(s) = 8 week(s).
  2. Due date = 2024-03-01 + 56 day(s) = 2024-04-26; the adjusted age is the age measured from that date.
  3. Born 2024-03-01 (a Friday); measuring on 2025-01-15.
  4. Whole years first: 2024-03-01 + 0 years lands on or before 2025-01-15.
  5. Then whole months and days: + 10 month(s) + 14 day(s) reaches 2025-01-15.
  6. Elapsed days = 320, i.e. 45 weeks and 5 day(s).
  7. Next birthday 2025-03-01 (Saturday), 45 day(s) away; turning 1.
