WHILE USING TMS (http://ircep.gov.in/TMS/Mst) TMS CALENDER IS INACTIVE

tms calender is for feeding date in some datas, the calender is inactive in my home pc ,but the same is active in my official pc..
let me know the software required for activation of calender

That web site requires a logon. Most likely the calendar object is part of an installation package that has been run on your "official" computer but hasn't been run on the home PC. I have no way of knowing how to get the install program without getting on the site.
