Planning timeline
How it works
The countdown is the whole number of days between today and your event date in your local time zone. The timeline anchors each milestone a set number of months before the event:
milestone date = event date − months before
Tasks whose date has already passed are ticked off. It is a condensed version of a typical 12-month wedding checklist, adjust to fit your own plans.
Your date never leaves your device, everything runs in your browser.
What this does
An event countdown calculator counts the days, weeks, and months to your event, with a condensed planning timeline that ticks off each milestone as its date passes.
How to use it
- Enter your event date.
- Read the days, weeks, and months left.
- Review the milestone timeline.
- See which tasks are already due.
How it works
The countdown is whole days in your local time zone, also shown as weeks and months. Each milestone is anchored a set number of months before the event and auto-checks once passed.
days left = event date − today
Understanding your result
The number of days is the headline, but the milestone timeline is what keeps you on track, so work it backwards and lock in the long-lead items, venue, then caterer and photographer, before the short-lead ones. Reading the gap in weeks or months helps you pace the work rather than leaving everything to a frantic final fortnight.
Example
An event 180 days away is about 26 weeks or 6 months out.
