Public holidays are known for 2026 and 2027, from the open-sourcepython-holidays data (MIT licence, version0.105). When you open this page, the location may be filled in from where your connection appears to be; nothing about it, or about your plan, is kept.
Questions people ask
How are the dates worked out?
Forward from the start date, in working days. A task starts on the first working day after the task it follows finishes, plus any gap you give it, and takes as many working days as you say. Weekends and the public holidays of the location you choose are skipped.
What if two tasks wait on each other?
The chart is not drawn, and the rows that wait on each other are named, because no order of them is a plan anybody wrote.
Can I keep the chart?
Yes. Download it as an Excel workbook with the weeks filled in as bars, as a CSV, or as a calendar file with one event per task. The address of the answer also holds the whole plan, so bookmarking it keeps it.
Is anything I type stored?
No. The plan travels in the address of the page and is used to draw the answer; nothing is kept.
