Cold email sequence date calculator: the send date of every step, weekends and holidays skipped
In short: Type a start date, the days between steps and any holidays. Choose to count sending days (Monday to Friday) or calendar days, and get the date and weekday of every step. Limit: It skips only weekends and the dates you list; it knows no public holidays.
Each step goes out a set number of days after the one before. Count sending days and weekends are skipped; count calendar days and you decide whether a step that lands on a weekend moves to the next sending day. Add holidays to skip them too. This calculator lists the date and weekday of every step.

Type the day you plan to start.
"3, 4, 7" is four steps: step 2 is 3 days after step 1, step 3 is 4 days after step 2, step 4 is 7 days after step 3.
Holidays, as YYYY-MM-DD, separated by commas or lines.
The numbers in the boxes are examples to show how it works. Replace every one with your own; nothing here is a benchmark.

| Step | Date | Day | Days after step 1 | How |
|---|---|---|---|---|
| 1 | 2026-11-16 | Monday | 0 | Start date |
| 2 | 2026-11-19 | Thursday | 3 | 3 sending days after step 1 |
| 3 | 2026-11-25 | Wednesday | 9 | 4 sending days after step 2 |
| 4 | 2026-12-07 | Monday | 21 | 7 sending days after step 3 |
The math, with your numbers
- Step 2 = 2026-11-16 + 3 sending days = 2026-11-19 (Thursday)
- Step 3 = 2026-11-19 + 4 sending days = 2026-11-25 (Wednesday)
- Step 4 = 2026-11-25 + 7 sending days = 2026-12-07 (Monday)
Next step
Every step goes to the same addresses as step 1.
A dead address bounces on step 1 and takes the rest of the sequence with it. Check the list before the first date on this page.

How do I work out the dates of a cold email sequence?
- Pick the day step 1 goes out.
- Enter the days between steps, separated by commas. "3, 4, 7" makes four steps.
- Choose how days are counted: sending days, or calendar days with or without moving weekend steps.
- Optionally list holidays with no sending, then read the date of every step.
Example
- You enter
- Step 1 on 2026-11-16, gaps of 3, 4 and 7 sending days, Monday to Friday counting and 2026-11-26 as a no-send date.
- You get
- Step 1 Monday 2026-11-16, step 2 Thursday 2026-11-19, step 3 Wednesday 2026-11-25 and step 4 Monday 2026-12-07, 21 days after step 1.
- Limits
- Runs in your browser; nothing is uploaded. It skips weekends and the dates you list, knows no public holidays and applies no time zones.
How are the dates counted?
In sending-day mode, a gap of 3 means the third Monday to Friday day after the step before, skipping weekends and the holidays you list. In calendar mode, a gap of 3 is three days on the calendar. With moving on, a step that lands on a weekend or a listed holiday goes to the next sending day.
If step 1 itself falls on a weekend or a listed holiday in the two modes that skip them, it moves to the next sending day and the table says so.
Why do the days between steps matter?
They set how long a sequence takes and how the load builds on your inboxes. Closer gaps finish sooner but stack more sends into each day. The dates here show the end of the sequence; the load is planned in the follow-up planner.
Choosing the day and hour within a day is a separate question. See best time to send email for the recipient's time zone.
Which days are not sending days?
Here, Saturdays and Sundays in the first two modes, plus the dates you list. The tool does not know public holidays in any country, so list those that matter for your recipients. It does not read the clock either: the start date is always the one you type.
Time zones are not applied. Dates are calendar dates, and a send at the end of your day may be the next day for a recipient far from you.
Who uses this tool, and for what?
- Cold emailers
- Know when the last step of a sequence goes out before telling a client.
- Agencies
- Put real dates in a campaign plan, with holidays left out.
- Marketers
- Plan a nurture sequence around a launch date.
- SDR teams
- Line up call tasks with the email steps.
What can’t this tool tell you?
- It skips only weekends and the dates you list; it knows no public holidays.
- Dates are calendar dates, with no time zones.
- It shows when steps are due, not whether your sending tool sends on that date.
- Gaps are the same for every contact; replies that stop a sequence are not modelled.
Common questions
- How do I list holidays?
- One date per line or separated by commas, written as YYYY-MM-DD, such as 2026-12-25. Dates it cannot read are listed so you can correct them.
- What is the difference between the modes?
- Sending days skip weekends while counting. Calendar days count every day, then optionally move a step off a weekend. The same gaps can end on different dates.
- Does it know public holidays?
- No. It only skips the dates you list.
- How many steps can it show?
- Up to 12, with gaps of 1 to 60 days.
- Does it take time zones into account?
- No. It works in calendar dates. Use the best time to send tool for the hour in your recipients' time zones.
- Is my data uploaded?
- No. It runs in your browser.
Authentication and capacity are half of deliverability.
The other half is who you send to. Every hard bounce counts against the domain and inboxes you are sending from, and nothing in DNS can tell you which addresses on your list are dead.
- Bulk verification with real SMTP mailbox checks
- Hard bounces removed before a send, not discovered after
- Catch-all, disposable and role detection on every row
