Add a date merge tag

Insert a dynamic date into a campaign or subject line, offset to past or future, formatted how you like.

1 min read Updated 10 Jun 2026

The [DATE] merge tag inserts a dynamic date into your subject line or content - today's date, or one offset from it. It's perfect for recurring newsletters, event reminders and deadlines, saving you editing the date by hand each time. One limit: you can't use [DATE] inside a link.

The syntax

The tag takes two parameters - a number and a format:

[DATE|0|format]

The number offsets the date in seconds from now: 0 is today, a positive number is the future, a negative number is the past.

The format controls how it's displayed, using PHP date conventions. Long-form dates like "Monday, June 10" are English-only.

Examples

If today is 10 June 2013:

  • [DATE|86400|m.d.y] shows 06.11.13 (86,400 seconds = 1 day ahead).
  • [DATE|-259200|F j, Y] shows June 07, 2013 (259,200 seconds = 3 days back).

Common formats

Format Output Description
Y-m-d 2013-06-10 Year-month-day (numeric)
F j, Y June 10, 2013 Full month, day, year
M d, Y Jun 10, 2013 Short month, day, year
m/d/Y 06/10/2013 Month/day/year
l, F j Monday, June 10 Weekday, month, day

Handy intervals

  • 1 day = 86,400 seconds
  • 1 week = 604,800 seconds
  • 30 days = 2,592,000 seconds

Troubleshooting

The date doesn't show, or shows wrong - follow the [DATE|seconds|format] syntax exactly, separate the parameters with pipes, and use valid PHP format codes. Start with a simple format like Y-m-d.

Wrong timezone - dates use the server timezone, not the recipient's, so allow for that and for daylight saving.

Calculations are off - double-check your seconds (86,400 = 1 day), and use negative for past, positive for future.
