268 days
38 weeks and 2 days. Counting today as well, it is 269 days.
What it counts
The number is the whole calendar days from the date you pick up to today. The date itself is the starting point, so yesterday gives 1. The line under the answer also gives the count with today included, which is the one people mean by "day 30 of the challenge" or "we have been together 100 days".
Days since the start of the year, since you quit smoking, since an order was placed: it is the same sum. For a date that is still ahead, use the countdown maker instead.
Questions people ask
How many days since 1 January?
The calculator opens on 1 January of this year, so the answer is already at the top of the page.
Is today counted?
Not in the big number. The note under it adds today, because anniversaries and streaks usually count the first day as day 1.
Can I get this in weeks or months?
Weeks are in the result. For months, the days between dates page explains why months do not divide evenly.
