mhc - Message Harmonized Calendaring system

This manual page documents briefly the mhc file format. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

Mhc file format is based on STD11/RFC822: Standard for the format of ARPA Internet text messages. In mhc file, the following extra header fields are used.

X-SC-Day:

Date of event in format yyyymmdd. You can specify multiple date with space separated like:

X-SC-Day: 19990409 19990413

which means April 9th 1999 and April 13th 1999.

X-SC-Time:

Time of event in format hh:mm-hh:mm or hh:mm. For event which has no meanings about time, you can leave it empty in this field.

X-SC-Duration:

Period of event in yyyymmdd-yyyymmdd. You can omit start date or end date, like "19991121-". X-SC-Duration: is used only to limit date specified by X-SC-Day: or X-SC-Cond, so you can't describe event date only by X-SC-Duration:. If X-SC-Duration: is empty, it means no limit.

X-SC-Cond:

Condition of event date by using following keyword. 00-31 Day of month. 1st 2nd 3rd 4th 5th Last Week in month. Sun Mon ... Sat Day of week. Jan Feb ... Dec Month

Examples,

X-SC-Cond: Tue Fri

Every Tuesday and Friday.

X-SC-Cond: 31 Aug

Every August 31th.

X-SC-Cond: 1st 3rd Fri

Every 1st and 3rd Friday.

X-SC-Cond: Fri

X-SC-Day: !19990409 Every Friday, but except April 9th 1999.

X-SC-Cond: Fri 13

Every 13th and Every Friday, not 13th Friday.

X-SC-Alarm:

X-SC-Alarm: 10 minutes

Alarm 10 minutes before event.

X-SC-Alarm: 3 hour

Alarm 3 day before event.
