fix an input date in calendar

Question

Is there any way that you can cutsomize the default calendar so that the user can only modify the year instead of the whole date? I want to fix the date to January 1st.

I have implemented a validation rule, so that the user cannot add a date that is not January 1st, but for filtering records and viewing them, the user can search any date and I want to be able to change this.

I thought about making a picklist containing years only, but I'll have to manually edit them.

If you are open to use Custom Visualforce page instead of standard Salesforce pages, here is a solution.

Get the Year through a Picklist or a textBox and build the complete date on your preferable action(i.e either on save, any button click or other events) through a function in controller.

Visualforce Markup

<apex:outputLabel value="1st January"/> &nbsp;
<apex:inputText value={!Year}/>

<apex:commandButton action="{!saveDate}" value="Save"/>

Controller:

public String Year{get;set}
public PageReference SaveDate()
{
Date finalDate = Date.parse('01/01/'+Year);
}
