Weeks Between Dates Calculator – Exact Weeks & Days
Calculate weeks between any two chosen dates
What this tool does. The Weeks Between Dates Calculator shows the exact number of full weeks between any two calendar dates, plus any extra days left over. Enter a start date, enter an end date, and the result comes back as a clean phrase like 6 weeks 1 day instead of a vague “about a month and a half.” It’s built to match the same clean layout as your other time & date tools: one white card, two clear rows for dates, and a bold, copyable answer.
How it works. You choose both dates using the dropdowns. The calculator validates that each is a real date (no impossible combinations, full leap year support), then figures out which one comes first. It counts the total number of days between them, divides by 7 to get whole weeks, and uses the remainder as extra days. The order you type them in doesn’t matter: if your “start” is actually later than your “end,” the tool flips them behind the scenes and labels them correctly as the earlier and later dates in the breakdown.
Exact weeks + days. Many planners and forms think in week blocks but still need precision. If the gap is an exact multiple of 7 days, you’ll see something like 10 weeks 0 days. If not, you’ll get a combined result such as 6 weeks 1 day, 3 weeks 4 days, or whatever the real remainder is. This makes it easy to answer questions like “How many full weeks are there between these dates?” without losing the leftover days that actually matter for deadlines, eligibility, contracts, and schedules.
Straight-line breakdown. The result card is designed so you can read, screenshot, or paste it without reconstruction. The headline explains the gap in weeks and days. The facts row directly under it lays out, in a single straight flow: the earlier date, the later date, the total days between, the full weeks, and the leftover days. No extra tables, no clutter, just a compact summary that lines up perfectly with your other calculators’ style.
Typical use cases. Use the Weeks Between Dates Calculator to check school terms, sprint counts, production timelines, medical or maternity schedules, event countdowns, program durations, or any period defined in weeks. For example: “How many weeks are there between contract start and end?”, “How many full weeks of training fit before race day?”, or “Is this person at least 6 weeks old by the cutoff date?”. Instead of manually counting calendar rows (and miscounting), you get a reliable answer in one click.
Step-by-step. Set the top row to your intended start date and the second row to your intended end date. Click Calculate weeks between or press Enter while focused in any dropdown. The calculator automatically determines which date is earlier and shows the result. To try another pair, simply change one or both dates and run it again — there’s no reset button to clutter the design.
How it relates to other tools. If you’d rather move forward from today by a fixed number of weeks, use the Weeks From Today Calculator. To shift a custom date by positive or negative weeks, use the Weeks Calculator. For pure day counts, the Days Since Date Calculator and Days From Today Calculator give you a similar experience. All of these pages use consistent wording and layout so users feel at home.
Accuracy & privacy. The math runs locally in your browser using real calendar rules, including leap years and month boundaries. No dates, ranges, or results are sent to a server, logged, or stored. As long as your device’s time and date settings are correct, the Weeks Between Dates Calculator gives you an accurate, trustworthy answer suitable for planning, documentation, and compliance checks.
FAQs
Does order matter?
No. Enter your two dates in any order. The calculator automatically finds the earlier and later date and bases the result on that.
Are the dates inclusive or exclusive?
By default this calculator counts the number of days between the two dates as a difference, not including the end date itself as an extra day. This is standard for duration math and makes the weeks + days breakdown consistent.
Can it show only full weeks?
Yes. Just read the “Full Weeks” value in the breakdown — that’s the number of complete 7-day blocks between your dates.
Does it handle leap years?
Yes. All calculations use actual calendar dates, so February 29 and varying month lengths are handled correctly.
