* `wnn` - Week. Defines either a week (1 to 53) within a previously defined year, or any year when no `y` information is given in a starting date; or a duration of nn weeks, i.e., nn*7 days. For example, `[(y1991M11d14h5m30s19) {w2}]` means from 14 November 1991 at 5:30:19 a.m. to 28 November 1991, 5:30:19 a.m. Notice that `{w1}` = `{d7}`

* `dnn` - Day. Defines either a particular day (1 to 28, 29, 30, 31) within a particular month if previously defined with the `M` format in a starting date; or a duration of nn days, i.e., nn*24 hours. For example, `[(y1991M11d14h5m30s19) {d2}]` means from 14 November 1991 at 5:30:19 a.m. to 16 November 1991, 5:30:19 a.m. Notice that `{d1}` = `{h24}`
* `tn` - Day. Only in starting date defines a particular weekday (`1`:Sunday, `2`:Monday, `3`:Tuesday, `4`:Wednesday, `5`:Thursday, `6`:Friday, `7`:Saturday) in a previously (if any) defined week. For example, `(M5t2)` means each Monday in the fifth month (May) of any year, at 0:00:00 a.m.
* `fxn` - Day. Only in starting date defines a particular weekday in a previously (if any) defined month, with the following rules: n is used as in the “t” format with the same domain of values, 1:Sunday up to 7:Saturday. For “x” one of the following values has to be substituted: 1:first, 2:second, 3:third, 4:fourth, 5:fifth. For example: `(...f12)` means the first Monday at 0:00:00 a.m.
* `lxn` - Day. Only in starting date defines a particular weekday in a previously (if any) defined month, with the following rules: n is used as for the “t” format with the same domain of values, `1`:Sunday up to `7`:Saturday. x has to be chosen from the following set: `1`:first, `2`:second, `3`:third, `4`:fourth, `5`:fifth. Values are given in reverse order starting from the end of the month and have the meaning: 1=last, 2=last but one, 3= last but two, etc. For example, `(...l12)` means the last Monday at 0:00:00 a.m.

* `hnn` - Hour. Defines either a particular hour (0 to 23) within a particular day (if previously defined) in a starting date; or a duration of nn hours, i.e., nn*60 minutes. For example, `[(y1991M11d14h5m30s19) {h10}]` means from 14 November 1991, 5:30:19 a.m. to 14 November 1991 at 3:30:19 p.m. Notice that `{h1}` = `{m60}`
* `mnn` - Minute. Defines either a particular minute (0 to 59) within a particular hour (if previously defined) in a starting date; or a duration of nn minutes, i.e., nn*60 seconds. For example, `[(y1991M11d14h5m30s19) {m11}]` means from 14 November 1991 at 5:30:19 a.m. to 14 November 1991 at 5:41:19 a.m. Notice that `{m1}` = `{s60}`
* `snn` - Second. Defines either a particular second (0 to 59) within a particular minute (if previously defined) in a starting date; or a duration of nn seconds. For example, `[(y1991M11d14h5m30s19) {s21}]` means from 14 November 1991 at 5:30:19 a.m. to 14 November 1991 at 5:30:40 a.m. Notice that `{m1}` = `{s60}`
