MonthSprig makes a little space for the plans you want to keep in view.

A calendar you can make your own

Choose real dates, add the events that matter to you and arrange a page you can read on paper. MonthSprig focuses on that small, practical job: monthly calendars, year overviews, academic ranges, weekly plans, quarterly pages and reusable birthday calendars.

The calendar begins with actual Gregorian dates, not a decorative picture of a grid. You can choose the first weekday, paper, orientation and amount of detail without searching for another template every time a preference changes.

Keep control of the details

Add a single event, a period covering several days or a weekly, monthly or yearly repeat. Optional time labels help a reader understand the page, while the underlying events remain date-based. An event on a nonexistent repeated date is skipped rather than silently moved.

CSV import helps with a list of events, and MonthSprig JSON restores an editable project. Both include a review step so a file does not replace useful work before you have checked what it contains.

Take the version you need

PDF and PNG are for the arranged calendar. Event CSV and ICS help you move the dates into another tool. JSON is the editable project copy to keep for later changes. Printing has a separate, uncluttered page without site navigation or advertisements.

A local save stays with the browser and device you are using. It is useful for returning to a project, but it is not cloud synchronization. A separate JSON backup is the practical way to keep a copy you can restore.

Know where the dates come from

Date grids use Gregorian calendar rules within the supported 1900–2100 range. The optional U.S. federal collection is based on OPM information reviewed for holiday years 2026–2028. Actual and observed dates remain distinct.

That collection does not claim to cover every school, region or organization. A 2028–2029 academic calendar displays its holiday coverage limit rather than filling unreviewed dates by assumption. The Methodology and Data sources pages explain those boundaries.

Use the guides as you go

The Blog covers planning and printing decisions with worked examples. The Docs provide the corresponding controls, file formats and recovery steps. You can begin with a blank page and one event, then add more once the preview fits the way you plan.
